Python API

+

(Py)Iceberg is catalog centric. Meaning that reading/writing data goes via a catalog. First step is to instantiate a catalog to load a table. Let's use the following configuration in .pyiceberg.yaml to define a REST catalog called prod:

+
catalog:
+  prod:
+    uri: http://rest-catalog/ws/
+    credential: t-1234:secret
+
+

Note that multiple catalogs can be defined in the same .pyiceberg.yaml, for example, in the case of a Hive and REST catalog:

+
catalog:
+  hive:
+    uri: thrift://127.0.0.1:9083
+    s3.endpoint: http://127.0.0.1:9000
+    s3.access-key-id: admin
+    s3.secret-access-key: password
+  rest:
+    uri: https://rest-server:8181/
+    warehouse: my-warehouse
+
+

The different catalogs can be loaded in PyIceberg by their name: load_catalog(name="hive") and load_catalog(name="rest"). An overview of the configuration options can be found on the configuration page.

+

This information must be placed inside a file called .pyiceberg.yaml located either in the $HOME or %USERPROFILE% directory (depending on whether the operating system is Unix-based or Windows-based, respectively), in the current working directory, or in the $PYICEBERG_HOME directory (if the corresponding environment variable is set).

+

It is also possible to load a catalog without using a .pyiceberg.yaml by passing in the properties directly:

+
from pyiceberg.catalog import load_catalog
+
+catalog = load_catalog(
+    "docs",
+    **{
+        "uri": "http://127.0.0.1:8181",
+        "s3.endpoint": "http://127.0.0.1:9000",
+        "py-io-impl": "pyiceberg.io.pyarrow.PyArrowFileIO",
+        "s3.access-key-id": "admin",
+        "s3.secret-access-key": "password",
+    }
+)
+
+

Next, create a namespace:

+
catalog.create_namespace("docs_example")
+
+

Or, list existing namespaces:

+
ns = catalog.list_namespaces()
+
+assert ns == [("docs_example",)]
+
+

Create a table

+

To create a table from a catalog:

+
from pyiceberg.schema import Schema
+from pyiceberg.types import (
+    TimestampType,
+    FloatType,
+    DoubleType,
+    StringType,
+    NestedField,
+    StructType,
+)
+
+schema = Schema(
+    NestedField(field_id=1, name="datetime", field_type=TimestampType(), required=True),
+    NestedField(field_id=2, name="symbol", field_type=StringType(), required=True),
+    NestedField(field_id=3, name="bid", field_type=FloatType(), required=False),
+    NestedField(field_id=4, name="ask", field_type=DoubleType(), required=False),
+    NestedField(
+        field_id=5,
+        name="details",
+        field_type=StructType(
+            NestedField(
+                field_id=4, name="created_by", field_type=StringType(), required=False
+            ),
+        ),
+        required=False,
+    ),
+)
+
+from pyiceberg.partitioning import PartitionSpec, PartitionField
+
+partition_spec = PartitionSpec(
+    PartitionField(
+        source_id=1, field_id=1000, transform="day", name="datetime_day"
+    )
+)
+
+from pyiceberg.table.sorting import SortOrder, SortField
+
+# Sort on the symbol
+sort_order = SortOrder(SortField(source_id=2, transform='identity'))
+
+catalog.create_table(
+    identifier="docs_example.bids",
+    schema=schema,
+    partition_spec=partition_spec,
+    sort_order=sort_order,
+)
+
+

When the table is created, all IDs in the schema are re-assigned to ensure uniqueness.

+

To create a table using a pyarrow schema:

+
import pyarrow as pa
+
+schema = pa.schema([
+        pa.field("foo", pa.string(), nullable=True),
+        pa.field("bar", pa.int32(), nullable=False),
+        pa.field("baz", pa.bool_(), nullable=True),
+])
+
+catalog.create_table(
+    identifier="docs_example.bids",
+    schema=schema,
+)
+
+

Another API to create a table is using the create_table_transaction. This follows the same APIs when making updates to a table. This is a friendly API for both setting the partition specification and sort-order, because you don't have to deal with field-IDs.

+
with catalog.create_table_transaction(identifier="docs_example.bids", schema=schema) as txn:
+    with txn.update_schema() as update_schema:
+        update_schema.add_column(path="new_column", field_type='string')
+
+    with txn.update_spec() as update_spec:
+        update_spec.add_identity("symbol")
+
+    txn.set_properties(test_a="test_aa", test_b="test_b", test_c="test_c")
+
+

Load a table

+

There are two ways of reading an Iceberg table; through a catalog, and by pointing at the Iceberg metadata directly. Reading through a catalog is preferred, and directly pointing at the metadata is read-only.

+

Catalog table

+

Loading the bids table:

+
table = catalog.load_table("docs_example.bids")
+# Equivalent to:
+table = catalog.load_table(("docs_example", "bids"))
+# The tuple syntax can be used if the namespace or table contains a dot.
+
+

This returns a Table that represents an Iceberg table that can be queried and altered.

+

Static table

+

To load a table directly from a metadata.json file (i.e., without using a catalog), you can use a StaticTable as follows:

+
from pyiceberg.table import StaticTable
+
+static_table = StaticTable.from_metadata(
+    "s3://warehouse/wh/nyc.db/taxis/metadata/00002-6ea51ce3-62aa-4197-9cf8-43d07c3440ca.metadata.json"
+)
+
+

The static-table does not allow for write operations. If your table metadata directory contains a version-hint.text file, you can just specify the table root path, and the latest metadata.json file will be resolved automatically:

+
from pyiceberg.table import StaticTable
+
+static_table = StaticTable.from_metadata(
+    "s3://warehouse/wh/nyc.db/taxis"
+)
+
+

Check if a table exists

+

To check whether the bids table exists:

+
catalog.table_exists("docs_example.bids")
+
+

Returns True if the table already exists.

+

Write to a table

+

Reading and writing is being done using Apache Arrow. Arrow is an in-memory columnar format for fast data interchange and in-memory analytics. Let's consider the following Arrow Table:

+
import pyarrow as pa
+
+df = pa.Table.from_pylist(
+    [
+        {"city": "Amsterdam", "lat": 52.371807, "long": 4.896029},
+        {"city": "San Francisco", "lat": 37.773972, "long": -122.431297},
+        {"city": "Drachten", "lat": 53.11254, "long": 6.0989},
+        {"city": "Paris", "lat": 48.864716, "long": 2.349014},
+    ],
+)
+
+

Next, create a table using the Arrow schema:

+
from pyiceberg.catalog import load_catalog
+
+catalog = load_catalog("default")
+
+tbl = catalog.create_table("default.cities", schema=df.schema)
+
+

Next, write the data to the table. Both append and overwrite produce the same result, since the table is empty on creation:

+ + +
+

Fast append

+

PyIceberg defaults to the fast append to minimize the amount of data written. This enables fast commit operations, reducing the possibility of conflicts. The downside of the fast append is that it creates more metadata than a merge commit. Compaction is planned and will automatically rewrite all the metadata when a threshold is hit, to maintain performant reads.

+
+ + +
tbl.append(df)
+
+# or
+
+tbl.overwrite(df)
+
+

Now, the data is written to the table, and the table can be read using tbl.scan().to_arrow():

+
pyarrow.Table
+city: string
+lat: double
+long: double
+----
+city: [["Amsterdam","San Francisco","Drachten","Paris"]]
+lat: [[52.371807,37.773972,53.11254,48.864716]]
+long: [[4.896029,-122.431297,6.0989,2.349014]]
+
+

If we want to add more data, we can use .append() again:

+
tbl.append(pa.Table.from_pylist(
+    [{"city": "Groningen", "lat": 53.21917, "long": 6.56667}],
+))
+
+

When reading the table tbl.scan().to_arrow() you can see that Groningen is now also part of the table:

+
pyarrow.Table
+city: string
+lat: double
+long: double
+----
+city: [["Amsterdam","San Francisco","Drachten","Paris"],["Groningen"]]
+lat: [[52.371807,37.773972,53.11254,48.864716],[53.21917]]
+long: [[4.896029,-122.431297,6.0989,2.349014],[6.56667]]
+
+

The nested lists indicate the different Arrow buffers. Each of the writes produce a Parquet file where each row group translates into an Arrow buffer. In the case where the table is large, PyIceberg also allows the option to stream the buffers using the Arrow RecordBatchReader, avoiding pulling everything into memory right away:

+
for buf in tbl.scan().to_arrow_batch_reader():
+    print(f"Buffer contains {len(buf)} rows")
+
+

To avoid any type inconsistencies during writing, you can convert the Iceberg table schema to Arrow:

+
df = pa.Table.from_pylist(
+    [{"city": "Groningen", "lat": 53.21917, "long": 6.56667}], schema=table.schema().as_arrow()
+)
+
+tbl.append(df)
+
+

You can delete some of the data from the table by calling tbl.delete() with a desired delete_filter. This will use the Iceberg metadata to only open up the Parquet files that contain relevant information.

+
tbl.delete(delete_filter="city == 'Paris'")
+
+

In the above example, any records where the city field value equals to Paris will be deleted. Running tbl.scan().to_arrow() will now yield:

+
pyarrow.Table
+city: string
+lat: double
+long: double
+----
+city: [["Amsterdam","San Francisco","Drachten"],["Groningen"]]
+lat: [[52.371807,37.773972,53.11254],[53.21917]]
+long: [[4.896029,-122.431297,6.0989],[6.56667]]
+
+

In the case of tbl.delete(delete_filter="city == 'Groningen'"), the whole Parquet file will be dropped without checking it contents, since from the Iceberg metadata PyIceberg can derive that all the content in the file matches the predicate.

+

Partial overwrites

+

When using the overwrite API, you can use an overwrite_filter to delete data that matches the filter before appending new data into the table. For example, consider the following Iceberg table:

+
import pyarrow as pa
+df = pa.Table.from_pylist(
+    [
+        {"city": "Amsterdam", "lat": 52.371807, "long": 4.896029},
+        {"city": "San Francisco", "lat": 37.773972, "long": -122.431297},
+        {"city": "Drachten", "lat": 53.11254, "long": 6.0989},
+        {"city": "Paris", "lat": 48.864716, "long": 2.349014},
+    ],
+)
+
+from pyiceberg.catalog import load_catalog
+catalog = load_catalog("default")
+
+tbl = catalog.create_table("default.cities", schema=df.schema)
+
+tbl.append(df)
+
+

You can overwrite the record of Paris with a record of New York:

+
from pyiceberg.expressions import EqualTo
+df = pa.Table.from_pylist(
+    [
+        {"city": "New York", "lat": 40.7128, "long": 74.0060},
+    ]
+)
+tbl.overwrite(df, overwrite_filter=EqualTo('city', "Paris"))
+
+

This produces the following result with tbl.scan().to_arrow():

+
pyarrow.Table
+city: large_string
+lat: double
+long: double
+----
+city: [["New York"],["Amsterdam","San Francisco","Drachten"]]
+lat: [[40.7128],[52.371807,37.773972,53.11254]]
+long: [[74.006],[4.896029,-122.431297,6.0989]]
+
+

If the PyIceberg table is partitioned, you can use tbl.dynamic_partition_overwrite(df) to replace the existing partitions with new ones provided in the dataframe. The partitions to be replaced are detected automatically from the provided arrow table. +For example, with an iceberg table with a partition specified on "city" field:

+
from pyiceberg.schema import Schema
+from pyiceberg.types import DoubleType, NestedField, StringType
+
+schema = Schema(
+    NestedField(1, "city", StringType(), required=False),
+    NestedField(2, "lat", DoubleType(), required=False),
+    NestedField(3, "long", DoubleType(), required=False),
+)
+
+tbl = catalog.create_table(
+    "default.cities",
+    schema=schema,
+    partition_spec=PartitionSpec(PartitionField(source_id=1, field_id=1001, transform=IdentityTransform(), name="city_identity"))
+)
+
+

And we want to overwrite the data for the partition of "Paris":

+
import pyarrow as pa
+
+df = pa.Table.from_pylist(
+    [
+        {"city": "Amsterdam", "lat": 52.371807, "long": 4.896029},
+        {"city": "San Francisco", "lat": 37.773972, "long": -122.431297},
+        {"city": "Drachten", "lat": 53.11254, "long": 6.0989},
+        {"city": "Paris", "lat": -48.864716, "long": -2.349014},
+    ],
+)
+tbl.append(df)
+
+

Then we can call dynamic_partition_overwrite with this arrow table:

+
df_corrected = pa.Table.from_pylist([
+    {"city": "Paris", "lat": 48.864716, "long": 2.349014}
+])
+tbl.dynamic_partition_overwrite(df_corrected)
+
+

This produces the following result with tbl.scan().to_arrow():

+
pyarrow.Table
+city: large_string
+lat: double
+long: double
+----
+city: [["Paris"],["Amsterdam"],["Drachten"],["San Francisco"]]
+lat: [[48.864716],[52.371807],[53.11254],[37.773972]]
+long: [[2.349014],[4.896029],[6.0989],[-122.431297]]
+
+

Upsert

+

PyIceberg supports upsert operations, meaning that it is able to merge an Arrow table into an Iceberg table. Rows are considered the same based on the identifier field. If a row is already in the table, it will update that row. If a row cannot be found, it will insert that new row.

+

Consider the following table, with some data:

+
from pyiceberg.schema import Schema
+from pyiceberg.types import IntegerType, NestedField, StringType
+
+import pyarrow as pa
+
+schema = Schema(
+    NestedField(1, "city", StringType(), required=True),
+    NestedField(2, "inhabitants", IntegerType(), required=True),
+    # Mark City as the identifier field, also known as the primary-key
+    identifier_field_ids=[1]
+)
+
+tbl = catalog.create_table("default.cities", schema=schema)
+
+arrow_schema = pa.schema(
+    [
+        pa.field("city", pa.string(), nullable=False),
+        pa.field("inhabitants", pa.int32(), nullable=False),
+    ]
+)
+
+# Write some data
+df = pa.Table.from_pylist(
+    [
+        {"city": "Amsterdam", "inhabitants": 921402},
+        {"city": "San Francisco", "inhabitants": 808988},
+        {"city": "Drachten", "inhabitants": 45019},
+        {"city": "Paris", "inhabitants": 2103000},
+    ],
+    schema=arrow_schema
+)
+tbl.append(df)
+
+

Next, we'll upsert a table into the Iceberg table:

+
df = pa.Table.from_pylist(
+    [
+        # Will be updated, the inhabitants has been updated
+        {"city": "Drachten", "inhabitants": 45505},

Inspecting tables

+

To explore the table metadata, tables can be inspected.

+ + +
+

Time Travel

+

To inspect a tables's metadata with the time travel feature, call the inspect table method with the snapshot_id argument. +Time travel is supported on all metadata tables except snapshots and refs. +

table.inspect.entries(snapshot_id=805611270568163028)
+

+
+ + +

Snapshots

Info

+

Content refers to type of content stored by the data file: 0 - Data, 1 - Position Deletes, 2 - Equality Deletes

+
+

To show only data files or delete files in the current snapshot, use table.inspect.data_files() and table.inspect.delete_files() respectively.

+

Add Files

+

Expert Iceberg users may choose to commit existing parquet files to the Iceberg table as data files, without rewriting them.

+ + +
+

Name Mapping and Field IDs

+

add_files can work with Parquet files both with and without field IDs in their metadata: +- Files with field IDs: When field IDs are present in the Parquet metadata, they must match the corresponding field IDs in the Iceberg table schema. This is common for files generated by tools like Spark or when using or other libraries with explicit field ID metadata. +- Files without field IDs: When field IDs are absent, the table must have a Name Mapping to map field names to Iceberg field IDs. add_files will automatically create a Name Mapping based on the table's current schema if one doesn't already exist.

+
+
+

Partitions

+

add_files only requires the client to read the existing parquet files' metadata footer to infer the partition value of each file. This implementation also supports adding files to Iceberg tables with partition transforms like MonthTransform, and TruncateTransform which preserve the order of the values after the transformation (Any Transform that has the preserves_order property set to True is supported). Please note that if the column statistics of the PartitionField's source column are not present in the parquet metadata, the partition value is inferred as None.

+
+
+

Maintenance Operations

+

Because add_files commits the existing parquet files to the Iceberg Table as any other data file, destructive maintenance operations like expiring snapshots will remove them.

+
+
+

Check Duplicate Files

+

The check_duplicate_files parameter determines whether the method validates that the specified file_paths do not already exist in the Iceberg table. When set to True (the default), the method performs a validation against the table’s current data files to prevent accidental duplication, helping to maintain data consistency by ensuring the same file is not added multiple times. While this check is important for data integrity, it can introduce performance overhead for tables with a large number of files. Setting check_duplicate_files=False can improve performance but increases the risk of duplicate files, which may lead to data inconsistencies or table corruption. It is strongly recommended to keep this parameter enabled unless duplicate file handling is strictly enforced elsewhere.

+
+ + +

Usage

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
ParameterRequired?TypeDescription
file_paths✔️List[str]The list of full file paths to be added as data files to the table
snapshot_propertiesDict[str, str]Properties to set for the new snapshot. Defaults to an empty dictionary
check_duplicate_filesboolWhether to check for duplicate files. Defaults to True
+

Example

+

Add files to Iceberg table:

+
# Given that these parquet files have schema consistent with the Iceberg table
+
+file_paths = [
+    "s3a://warehouse/default/existing-1.parquet",
+    "s3a://warehouse/default/existing-2.parquet",
+]
+
+# They can be added to the table without rewriting them
+
+tbl.add_files(file_paths=file_paths)
+
+# A new snapshot is committed to the table with manifests pointing to the existing parquet files
+
+

Add files to Iceberg table with custom snapshot properties:

+
# Assume an existing Iceberg table object `tbl`
+
+file_paths = [
+    "s3a://warehouse/default/existing-1.parquet",
+    "s3a://warehouse/default/existing-2.parquet",
+]
+
+# Custom snapshot properties
+snapshot_properties = {"abc": "def"}
+
+# Enable duplicate file checking
+check_duplicate_files = True
+
+# Add the Parquet files to the Iceberg table without rewriting
+tbl.add_files(
+    file_paths=file_paths,
+    snapshot_properties=snapshot_properties,
+    check_duplicate_files=check_duplicate_files
+)
+
+# NameMapping must have been set to enable reads
+assert tbl.name_mapping() is not None
+
+# Verify that the snapshot property was set correctly
+assert tbl.metadata.snapshots[-1].summary["abc"] == "def"
+
+

Schema evolution

+

PyIceberg supports full schema evolution through the Python API. It takes care of setting the field-IDs and makes sure that only non-breaking changes are done (can be overridden).

+

In the examples below, the .update_schema() is called from the table itself.

+
with table.update_schema() as update:
+    update.add_column("some_field", IntegerType(), "doc")
+
+

You can also initiate a transaction if you want to make more changes than just evolving the schema:

+
with table.transaction() as transaction:
+    with transaction.update_schema() as update_schema:
+        update.add_column("some_other_field", IntegerType(), "doc")
+    # ... Update properties etc
+
+

Union by Name

+

Using .union_by_name() you can merge another schema into an existing schema without having to worry about field-IDs:

+
from pyiceberg.catalog import load_catalog
+from pyiceberg.schema import Schema
+from pyiceberg.types import NestedField, StringType, DoubleType, LongType
+
+catalog = load_catalog()
+
+schema = Schema(
+    NestedField(1, "city", StringType(), required=False),
+    NestedField(2, "lat", DoubleType(), required=False),
+    NestedField(3, "long", DoubleType(), required=False),
+)
+
+table = catalog.create_table("default.locations", schema)
+
+new_schema = Schema(
+    NestedField(1, "city", StringType(), required=False),
+    NestedField(2, "lat", DoubleType(), required=False),
+    NestedField(3, "long", DoubleType(), required=False),
+    NestedField(10, "population", LongType(), required=False),
+)
+
+with table.update_schema() as update:
+    update.union_by_name(new_schema)
+
+

Now the table has the union of the two schemas print(table.schema()):

+
table {
+  1: city: optional string
+  2: lat: optional double
+  3: long: optional double
+  4: population: optional long
+}
+
+

Add column

+

Using add_column you can add a column, without having to worry about the field-id:

+
with table.update_schema() as update:
+    update.add_column("retries", IntegerType(), "Number of retries to place the bid")
+    # In a struct
+    update.add_column("details", StructType())
+
+with table.update_schema() as update:
+    update.add_column(("details", "confirmed_by"), StringType(), "Name of the exchange")
+
+

A complex type must exist before columns can be added to it. Fields in complex types are added in a tuple.

+

Rename column

+

Renaming a field in an Iceberg table is simple:

+
with table.update_schema() as update:
+    update.rename_column("retries", "num_retries")
+    # This will rename `confirmed_by` to `processed_by` in the `details` struct
+    update.rename_column(("details", "confirmed_by"), "processed_by")
+
+

Move column

+

Move order of fields:

+
with table.update_schema() as update:
+    update.move_first("symbol")
+    # This will move `bid` after `ask`
+    update.move_after("bid", "ask")
+    # This will move `confirmed_by` before `exchange` in the `details` struct
+    update.move_before(("details", "confirmed_by"), ("details", "exchange"))
+
+

Update column

+

Update a fields' type, description or required.

+
with table.update_schema() as update:
+    # Promote a float to a double
+    update.update_column("bid", field_type=DoubleType())
+    # Make a field optional
+    update.update_column("symbol", required=False)
+    # Update the documentation
+    update.update_column("symbol", doc="Name of the share on the exchange")
+
+

Be careful, some operations are not compatible, but can still be done at your own risk by setting allow_incompatible_changes:

+
with table.update_schema(allow_incompatible_changes=True) as update:
+    # Incompatible change, cannot require an optional field
+    update.update_column("symbol", required=True)
+
+

Delete column

+

Delete a field, careful this is a incompatible change (readers/writers might expect this field):

+
with table.update_schema(allow_incompatible_changes=True) as update:
+    update.delete_column("some_field")
+    # In a struct
+    update.delete_column(("details", "confirmed_by"))
+
+

Partition evolution

+

PyIceberg supports partition evolution. See the partition evolution +for more details.

+

The API to use when evolving partitions is the update_spec API on the table.

+
with table.update_spec() as update:
+    update.add_field("id", BucketTransform(16), "bucketed_id")
+    update.add_field("event_ts", DayTransform(), "day_ts")
+
+

Updating the partition spec can also be done as part of a transaction with other operations.

+
with table.transaction() as transaction:
+    with transaction.update_spec() as update_spec:
+        update_spec.add_field("id", BucketTransform(16), "bucketed_id")
+        update_spec.add_field("event_ts", DayTransform(), "day_ts")
+    # ... Update properties etc
+
+

Add fields

+

New partition fields can be added via the add_field API which takes in the field name to partition on, +the partition transform, and an optional partition name. If the partition name is not specified, +one will be created.

+
with table.update_spec() as update:
+    update.add_field("id", BucketTransform(16), "bucketed_id")
+    update.add_field("event_ts", DayTransform(), "day_ts")
+    # identity is a shortcut API for adding an IdentityTransform
+    update.identity("some_field")
+
+

Remove fields

+

Partition fields can also be removed via the remove_field API if it no longer makes sense to partition on those fields.

+
with table.update_spec() as update:
+    # Remove the partition field with the name
+    update.remove_field("some_partition_name")
+
+

Rename fields

+

Partition fields can also be renamed via the rename_field API.

+
with table.update_spec() as update:
+    # Rename the partition field with the name bucketed_id to sharded_id
+    update.rename_field("bucketed_id", "sharded_id")
+
+

Sort order updates

+

Users can update the sort order on existing tables for new data. See sorting for more details.

+

The API to use when updating a sort order is the update_sort_order API on the table.

+

Sort orders can only be updated by adding a new sort order. They cannot be deleted or modified.

+

Updating a sort order on a table

+

To create a new sort order, you can use either the asc or desc API depending on whether you want you data sorted in ascending or descending order. Both take the name of the field, the sort order transform, and a null order that describes the order of null values when sorted.

+
with table.update_sort_order() as update:
+    update.desc("event_ts", DayTransform(), NullOrder.NULLS_FIRST)
+    update.asc("some_field", IdentityTransform(), NullOrder.NULLS_LAST)
+
+

Table properties

+

Set and remove properties through the Transaction API:

+
with table.transaction() as transaction:
+    transaction.set_properties(abc="def")
+
+assert table.properties == {"abc": "def"}
+
+with table.transaction() as transaction:
+    transaction.remove_properties("abc")
+
+assert table.properties == {}
+
+

Or, without context manager:

+
table = table.transaction().set_properties(abc="def").commit_transaction()
+
+assert table.properties == {"abc": "def"}
+
+table = table.transaction().remove_properties("abc").commit_transaction()
+
+assert table.properties == {}
+
+

Snapshot properties

+

Optionally, Snapshot properties can be set while writing to a table using append or overwrite API:

+
tbl.append(df, snapshot_properties={"abc": "def"})
+
+# or
+
+tbl.overwrite(df, snapshot_properties={"abc": "def"})
+
+assert tbl.metadata.snapshots[-1].summary["abc"] == "def"
+
+

Snapshot Management

+

Manage snapshots with operations through the Table API:

+
# To run a specific operation
+table.manage_snapshots().create_tag(snapshot_id, "tag123").commit()
+# To run multiple operations
+table.manage_snapshots()
+    .create_tag(snapshot_id1, "tag123")
+    .create_tag(snapshot_id2, "tag456")
+    .commit()
+# Operations are applied on commit.
+
+

You can also use context managers to make more changes:

+
with table.manage_snapshots() as ms:
+    ms.create_branch(snapshot_id1, "Branch_A").create_tag(snapshot_id2, "tag789")
+
+

Tags

+

Tags are named references to snapshots that are immutable. They can be used to mark important snapshots for long-term retention or to reference specific table versions.

+

Create a tag pointing to a specific snapshot:

+
# Create a tag with default retention
+table.manage_snapshots().create_tag(
+    snapshot_id=snapshot_id,
+    tag_name="v1.0.0"
+).commit()
+
+# Create a tag with custom max reference age
+table.manage_snapshots().create_tag(
+    snapshot_id=snapshot_id,
+    tag_name="v1.0.0",
+    max_ref_age_ms=604800000  # 7 days
+).commit()
+
+

Remove an existing tag:

+
table.manage_snapshots().remove_tag("v1.0.0").commit()
+
+

Branching

+

Branches are mutable named references to snapshots that can be updated over time. They allow for independent lineages of table changes, enabling use cases like development branches, testing environments, or parallel workflows.

+

Create a branch pointing to a specific snapshot:

+
# Create a branch with default settings
+table.manage_snapshots().create_branch(
+    snapshot_id=snapshot_id,
+    branch_name="dev"
+).commit()
+
+# Create a branch with retention policies
+table.manage_snapshots().create_branch(
+    snapshot_id=snapshot_id,
+    branch_name="dev",
+    max_ref_age_ms=604800000,        # Max age of the branch reference (7 days)
+    max_snapshot_age_ms=259200000,   # Max age of snapshots to keep (3 days)
+    min_snapshots_to_keep=10         # Minimum number of snapshots to retain
+).commit()
+
+

Remove an existing branch:

+
table.manage_snapshots().remove_branch("dev").commit()
+
+

Table Maintenance

+

PyIceberg provides table maintenance operations through the table.maintenance API. This provides a clean interface for performing maintenance tasks like snapshot expiration.

+

Snapshot Expiration

+

Expire old snapshots to clean up table metadata and reduce storage costs:

+
# Expire snapshots older than three days
+from datetime import datetime, timedelta
+table.maintenance.expire_snapshots().older_than(
+    datetime.now() - timedelta(days=3)
+).commit()
+
+# Expire a specific snapshot by ID
+table.maintenance.expire_snapshots().by_id(12345).commit()
+
+# Context manager usage (recommended for multiple operations)
+with table.maintenance.expire_snapshots() as expire:
+    expire.by_id(12345)
+    expire.by_id(67890)
+    # Automatically commits when exiting the context
+
+

Real-world Example

+
def cleanup_old_snapshots(table_name: str, snapshot_ids: list[int]):
+    """Remove specific snapshots from a table."""
+    catalog = load_catalog("production")
+    table = catalog.load_table(table_name)
+
+    # Use context manager for safe transaction handling
+    with table.maintenance.expire_snapshots() as expire:
+        for snapshot_id in snapshot_ids:
+            expire.by_id(snapshot_id)
+
+    print(f"Expired {len(snapshot_ids)} snapshots from {table_name}")
+
+# Usage
+cleanup_old_snapshots("analytics.user_events", [12345, 67890, 11111])
+
+

Views

+

PyIceberg supports view operations.

+

Check if a view exists

+
from pyiceberg.catalog import load_catalog
+
+catalog = load_catalog("default")
+catalog.view_exists("default.bar")
+
+

Table Statistics Management

+

Manage table statistics with operations through the Table API:

+
# To run a specific operation
+table.update_statistics().set_statistics(statistics_file=statistics_file).commit()
+# To run multiple operations
+table.update_statistics()
+  .set_statistics(statistics_file1)
+  .remove_statistics(snapshot_id2)
+  .commit()
+# Operations are applied on commit.
+
+

You can also use context managers to make more changes:

+
with table.update_statistics() as update:
+    update.set_statistics(statistics_file)
+    update.remove_statistics(snapshot_id2)
+
+

Query the data

+

To query a table, a table scan is needed. A table scan accepts a filter, columns, optionally a limit and a snapshot ID:

+
from pyiceberg.catalog import load_catalog
+from pyiceberg.expressions import GreaterThanOrEqual
+
+catalog = load_catalog("default")
+table = catalog.load_table("nyc.taxis")
+
+scan = table.scan(
+    row_filter=GreaterThanOrEqual("trip_distance", 10.0),
+    selected_fields=("VendorID", "tpep_pickup_datetime", "tpep_dropoff_datetime"),
+    limit=100,
+)
+
+# Or filter using a string predicate
+scan = table.scan(
+    row_filter="trip_distance > 10.0",
+)
+
+[task.file.file_path for task in scan.plan_files()]
+
+

The low level API plan_files methods returns a set of tasks that provide the files that might contain matching rows:

+
[
+  "s3://warehouse/wh/nyc/taxis/data/00003-4-42464649-92dd-41ad-b83b-dea1a2fe4b58-00001.parquet"
+]
+
+

In this case it is up to the engine itself to filter the file itself. Below, to_arrow() and to_duckdb() that already do this for you.

+

Apache Arrow

+ + +
+

Requirements

+

This requires pyarrow to be installed.

+
+ + +

Using PyIceberg it is filter out data from a huge table and pull it into a PyArrow table:

+
table.scan(
+    row_filter=GreaterThanOrEqual("trip_distance", 10.0),
+    selected_fields=("VendorID", "tpep_pickup_datetime", "tpep_dropoff_datetime"),
+).to_arrow()
+
+

This will return a PyArrow table:

+
pyarrow.Table
+VendorID: int64
+tpep_pickup_datetime: timestamp[us, tz=+00:00]
+tpep_dropoff_datetime: timestamp[us, tz=+00:00]
+----
+VendorID: [[2,1,2,1,1,...,2,2,2,2,2],[2,1,1,1,2,...,1,1,2,1,2],...,[2,2,2,2,2,...,2,6,6,2,2],[2,2,2,2,2,...,2,2,2,2,2]]
+tpep_pickup_datetime: [[2021-04-01 00:28:05.000000,...,2021-04-30 23:44:25.000000]]
+tpep_dropoff_datetime: [[2021-04-01 00:47:59.000000,...,2021-05-01 00:14:47.000000]]
+
+

This will only pull in the files that that might contain matching rows.

+

One can also return a PyArrow RecordBatchReader, if reading one record batch at a time is preferred:

+
table.scan(
+    row_filter=GreaterThanOrEqual("trip_distance", 10.0),
+    selected_fields=("VendorID", "tpep_pickup_datetime", "tpep_dropoff_datetime"),
+).to_arrow_batch_reader()
+
+

Pandas

+ + +
+

Requirements

+

This requires pandas to be installed.

+
+ + +

PyIceberg makes it easy to filter out data from a huge table and pull it into a Pandas dataframe locally. This will only fetch the relevant Parquet files for the query and apply the filter. This will reduce IO and therefore improve performance and reduce cost.

+
table.scan(
+    row_filter="trip_distance >= 10.0",
+    selected_fields=("VendorID", "tpep_pickup_datetime", "tpep_dropoff_datetime"),
+).to_pandas()
+
+

This will return a Pandas dataframe:

+

+
+[116981 rows x 3 columns]
+
+

It is recommended to use Pandas 2 or later, because it stores the data in an Apache Arrow backend which avoids copies of data.

+

DuckDB

+ + +
+

Requirements

+

This requires DuckDB to be installed.

+
+ + +

A table scan can also be converted into a in-memory DuckDB table:

+
con = table.scan(
+    row_filter=GreaterThanOrEqual("trip_distance", 10.0),
+    selected_fields=("VendorID", "tpep_pickup_datetime", "tpep_dropoff_datetime"),
+).to_duckdb(table_name="distant_taxi_trips")
+
+

Using the cursor that we can run queries on the DuckDB table:

+
print(
+    con.execute(
+        "SELECT tpep_dropoff_datetime - tpep_pickup_datetime AS duration FROM distant_taxi_trips LIMIT 4"
+    ).fetchall()
+)
+[
+    (datetime.timedelta(seconds=1194),),
+    (datetime.timedelta(seconds=1118),),
+    (datetime.timedelta(seconds=1697),),
+    (datetime.timedelta(seconds=1581),),
+]
+
+

Ray

+ + +
+

Requirements

+

This requires Ray to be installed.

+
+ + +

A table scan can also be converted into a Ray dataset:

+
ray_dataset = table.scan(
+    row_filter=GreaterThanOrEqual("trip_distance", 10.0),
+    selected_fields=("VendorID", "tpep_pickup_datetime", "tpep_dropoff_datetime"),
+).to_ray()
+
+

This will return a Ray dataset:

+
Dataset(
+    num_blocks=1,
+    num_rows=1168798,
+    schema={
+        VendorID: int64,
+        tpep_pickup_datetime: timestamp[us, tz=UTC],
+        tpep_dropoff_datetime: timestamp[us, tz=UTC]
+    }
+)
+
+

Using Ray Dataset API to interact with the dataset:

+
print(ray_dataset.take(2))
+[
+    {
+        "VendorID": 2,
+        "tpep_pickup_datetime": datetime.datetime(2008, 12, 31, 23, 23, 50),
+        "tpep_dropoff_datetime": datetime.datetime(2009, 1, 1, 0, 34, 31),
+    },
+    {
+        "VendorID": 2,
+        "tpep_pickup_datetime": datetime.datetime(2008, 12, 31, 23, 5, 3),
+        "tpep_dropoff_datetime": datetime.datetime(2009, 1, 1, 16, 10, 18),
+    },
+]
+
+

Bodo

+

PyIceberg interfaces closely with Bodo Dataframes (see Bodo Iceberg Quick Start), +which provides a drop-in replacement for Pandas that applies query, compiler and HPC optimizations automatically. +Bodo accelerates and scales Python code from single laptops to large clusters without code rewrites.

+ + +
+

Requirements

+

This requires bodo to be installed.

+
+
pip install pyiceberg['bodo']
+
+ + +

A table can be read easily into a Bodo Dataframe to perform Pandas operations:

+
df = table.to_bodo()  # equivalent to `bodo.pandas.read_iceberg_table(table)`
+df = df[df["trip_distance"] >= 10.0]
+df = df[["VendorID", "tpep_pickup_datetime", "tpep_dropoff_datetime"]]
+print(df)
+
+

This creates a lazy query, optimizes it, and runs it on all available cores (print triggers execution):

+
        VendorID tpep_pickup_datetime tpep_dropoff_datetime
+0              2  2023-01-01 00:27:12   2023-01-01 00:49:56
+1              2  2023-01-01 00:09:29   2023-01-01 00:29:23

+...          ...                  ...                   ...
+245478         2  2023-01-31 22:32:57   2023-01-31 23:01:48
+245479         2  2023-01-31 22:03:26   2023-01-31 22:46:13
+245480         2  2023-01-31 23:25:56   2023-02-01 00:05:42
+245481         2  2023-01-31 23:18:00   2023-01-31 23:46:00
+245482         2  2023-01-31 23:18:00   2023-01-31 23:41:00
+
+[245483 rows x 3 columns]
+
+

Bodo is optimized to take advantage of Iceberg features such as hidden partitioning and various statistics for efficient reads.

+

Daft

+

PyIceberg interfaces closely with Daft Dataframes (see also: Daft integration with Iceberg) which provides a full lazily optimized query engine interface on top of PyIceberg tables.

+ + +
+

Requirements

+

This requires Daft to be installed.

+
+ + +

A table can be read easily into a Daft Dataframe:

+
df = table.to_daft()  # equivalent to `daft.read_iceberg(table)`
+df = df.where(df["trip_distance"] >= 10.0)
+df = df.select("VendorID", "tpep_pickup_datetime", "tpep_dropoff_datetime")
+
+

This returns a Daft Dataframe which is lazily materialized. Printing df will display the schema:

+
╭──────────┬───────────────────────────────┬───────────────────────────────╮
+│ VendorID ┆ tpep_pickup_datetime          ┆ tpep_dropoff_datetime         │
+│ ---      ┆ ---                           ┆ ---                           │
+│ Int64    ┆ Timestamp(Microseconds, None) ┆ Timestamp(Microseconds, None) │
+╰──────────┴───────────────────────────────┴───────────────────────────────╯
+
+(No data to display: Dataframe not materialized)
+
+

We can execute the Dataframe to preview the first few rows of the query with df.show().

+

This is correctly optimized to take advantage of Iceberg features such as hidden partitioning and file-level statistics for efficient reads.

+
df.show(2)
+
+
╭──────────┬───────────────────────────────┬───────────────────────────────╮
+│ VendorID ┆ tpep_pickup_datetime          ┆ tpep_dropoff_datetime         │

Polars

+

PyIceberg interfaces closely with Polars Dataframes and LazyFrame which provides a full lazily optimized query engine interface on top of PyIceberg tables.

+ + +
+

Requirements

+

This requires polars to be installed.

+
+
pip install pyiceberg['polars']
+
+ + +

PyIceberg data can be analyzed and accessed through Polars using either DataFrame or LazyFrame. +If your code utilizes the Apache Iceberg data scanning and retrieval API and then analyzes the resulting DataFrame in Polars, use the table.scan().to_polars() API. +If the intent is to utilize Polars' high-performance filtering and retrieval functionalities, use LazyFrame exported from the Iceberg table with the table.to_polars() API.

+
# Get LazyFrame
+iceberg_table.to_polars()
+
+# Get Data Frame
+iceberg_table.scan().to_polars()
+
+

Working with Polars DataFrame

+

PyIceberg makes it easy to filter out data from a huge table and pull it into a Polars dataframe locally. This will only fetch the relevant Parquet files for the query and apply the filter. This will reduce IO and therefore improve performance and reduce cost.

+
schema = Schema(
+    NestedField(field_id=1, name='ticket_id', field_type=LongType(), required=True),
+    NestedField(field_id=2, name='customer_id', field_type=LongType(), required=True),
+    NestedField(field_id=3, name='issue', field_type=StringType(), required=False),
+    NestedField(field_id=4, name='created_at', field_type=TimestampType(), required=True),
+  required=True
+)
+
+iceberg_table = catalog.create_table(
+    identifier='default.product_support_issues',
+    schema=schema
+)
+
+pa_table_data = pa.Table.from_pylist(
+    [
+        {'ticket_id': 1, 'customer_id': 546, 'issue': 'User Login issue', 'created_at': 1650020000000000},

+        {'ticket_id': 17, 'customer_id': 562, 'issue': 'Duplicate charge', 'created_at': 1650158240000000},
+        {'ticket_id': 18, 'customer_id': 563, 'issue': 'Unable to update profile', 'created_at': 1650166880000000},

+        {'ticket_id': 20, 'customer_id': 565, 'issue': 'Unable to download invoice', 'created_at': 1650184160000000},
+        {'ticket_id': 21, 'customer_id': 566, 'issue': 'Incorrect billing amount', 'created_at': 1650192800000000},

+
+iceberg_table.append(
+    df=pa_table_data
+)
+
+table.scan(
+    row_filter="ticket_id > 10",
+).to_polars()
+
+

This will return a Polars DataFrame:

Working with Polars LazyFrame

+

PyIceberg supports creation of a Polars LazyFrame based on an Iceberg Table.

+

using the above code example:

+
lf = iceberg_table.to_polars().filter(pl.col("ticket_id") > 10)
+print(lf.collect())
+
+

This above code snippet returns a Polars LazyFrame and defines a filter to be executed by Polars:

+

Apache DataFusion

+

PyIceberg integrates with Apache DataFusion through the Custom Table Provider interface (FFI_TableProvider) exposed through iceberg-rust.

+ + +
+

Requirements

+

This requires datafusion and pyiceberg-core to be installed.

+
+ + + + +
+

Experimental Feature

+

The DataFusion integration is considered experimental.

+

The integration has a few caveats:

+
    +
  • Only works with datafusion >= 45, < 49
    • +
  • Depends directly on iceberg-rust instead of PyIceberg's implementation
    • +
  • Has limited features compared to the full PyIceberg API
    • +
+

The integration will improve as both DataFusion and iceberg-rust matures.

+
+ + +

PyIceberg tables can be registered directly with DataFusion's SessionContext using the table provider interface.

+
from datafusion import SessionContext
+from pyiceberg.catalog import load_catalog
+import pyarrow as pa
+
+# Load catalog and create/load a table
+catalog = load_catalog("catalog", type="in-memory")
+catalog.create_namespace_if_not_exists("default")
+
+# Create some sample data
+data = pa.table({"x": [1, 2, 3], "y": [4, 5, 6]})
+iceberg_table = catalog.create_table("default.test", schema=data.schema)
+iceberg_table.append(data)
+
+# Register the table with DataFusion
+ctx = SessionContext()
+ctx.register_table_provider("test", iceberg_table)
+
+# Query the table using DataFusion SQL
+ctx.table("test").show()
+
+

This will output:

+
DataFrame()
++---+---+
+| x | y |
++---+---+
+| 1 | 4 |

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param observerOrNext Either an {@link Observer} with some or all callback methods,\n * or the `next` handler that is called for each value emitted from the subscribed Observable.\n * @param error A handler for a terminal event resulting from an error.
