How The Kafka Project Handles Clients

Starting with the 0.8 release we are maintaining all but the jvm client external to the main code base. The reason for this is that it allows a small group of implementers who know the language of that client to quickly iterate on their code base on their own release cycle. Having these maintained centrally was becoming a bottleneck as the main committers can't hope to know every possible programming language to be able to perform meaningful code review and testing. This lead to a scenario where the committers were attempting to review and test code they didn't understand.

...

If you are aware of other clients not listed here (or are the author of such a client), please add it here. Please also feel free to help fill out information on the features the client supports, level of activity of the project, level of documentation, etc.

For 0.8.x

The 0.8 release changes the protocol fairly substantially. The new protocol is documented here.

Producer Daemon

Bruce is a producer daemon that supports clients in various programming languages. Clients write messages to Bruce's UNIX domain datagram socket in a simple binary format. Bruce then takes full responsibility for reliable message delivery. Monitoring infrastructure can query Bruce's web interface for JSON-based status and data quality reports.
