postgresql-netty - an async Netty/NIO based PostgreSQL driver written in Scala

The main goal of this project is to implement a performant and fully functional async PostgreSQL driver. This project has no interest in JDBC, it's supposed to be a clean room implementation for people interested in talking directly to PostgreSQL.

PostgreSQL protocol information and definition can be found here

What can it do now?

connect to a database with or without authentication (supports MD5 and cleartext authentication methods)
receive database parameters
receive database notices
execute direct queries (without portals/prepared statements)
portals/prepared statements
parses most of the basic PostgreSQL types, other types are parsed as string
date, time and timestamp types are handled as JodaTime objects and not as java.util.Date objects
all work is done using the new scala.concurrent.Future and scala.concurrent.Promise objects

What is missing?

more authentication mechanisms
benchmarks
more tests (run the jacoco:cover sbt task and see where you can improve)
timeout handler for initial handshare and queries
implement byte array support

What are the design goals?

fast, fast and faster
small memory footprint
avoid copying data as much as possible (we're always trying to use wrap and slice on buffers)
easy to use, call a method, get a future or a callback and be happy
never, ever, block
all features covered by tests

How can I help?

checkout the source code
find bugs, find places where performance can be improved
check the What is missing piece
