RabbitMQ Stream Java Client

The RabbitMQ Stream Java Client is a Java library to communicate with the RabbitMQ Stream Plugin. It allows to create and delete streams, as well as to publish to and consume from these streams. This library requires at least Java 8, but Java 11 or more is recommended. See the overview for a quick glance at the features.

Stream PerfTest is a performance testing tool based on this client library.

Please refer to the documentation to find out more.

Versioning

The RabbitMQ Stream Java Client is in development and stabilization phase. When the stabilization phase ends, a 1.0.0 version will be cut, and semantic versioning is likely to be enforced.

Before reaching the stable phase, the client will use a versioning scheme of [0.MINOR.PATCH] where:

0 indicates the project is still in a stabilization phase.
MINOR is a 0-based number incrementing with each new release cycle. It generally reflects significant changes like new features and potentially some programming interfaces changes.
PATCH is a 0-based number incrementing with each service release, that is bux fixes.

Breaking changes between releases can happen but will be kept to a minimum.

Build Instructions

You need JDK 8 or later installed.

To build the JAR file:

./mvnw clean package -DskipITs -DskipTests

Running Tests with Docker

Launch the broker:

docker run -it --rm --name rabbitmq -p 5552:5552 -p 5672:5672 \
    -e RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS='-rabbitmq_stream advertised_host localhost' \
    rabbitmq:4.0

Enable the stream plugin:

docker exec rabbitmq rabbitmq-plugins enable rabbitmq_stream

Launch the tests:

./mvnw test -Drabbitmqctl.bin=DOCKER:rabbitmq

Running Tests with a Local Broker

To launch the test suite (requires a local RabbitMQ node with stream plugin enabled):

./mvnw verify -Drabbitmqctl.bin=/path/to/rabbitmqctl

Code Format

The project uses the Google Java Format. Read the documentation to support the format in your favorite IDE.
