develop customized producer and consumer in java

["Yu, Libo " <li...@citi.com>]

Hi,

I have read many documentation about Kafka but am still confused about
the Java development . If I want to integrate kafka into our system, I need
to write my own producer and consumer in Java. It is not very clear to me
what Java APIs are available to client developers and there is no detailed
documentation for those APIs. The other thing is about compiling. How to
find all the required jars to compile a customized producer and consumer?
Do I need to learn Scala? I will appreciate if anyone can give me some details.

Regards,

Libo

To write the client code, you can follow the examples in
http://kafka.apache.org/quickstart.html (0.7) or
https://cwiki.apache.org/confluence/display/KAFKA/0.8.0+Producer+Example(0.8).

You don't need to know scala to write the clients in java, but you do need
the scala jar at runtime.

In 0.8, if you run the following, all dependant jars will be included in
the release zip or tar file.
./sbt update
./sbt package
./sbt release-zip (or ./sbt release-tar)

Thanks,

Jun

Hi,

The API docs are here
-http://people.apache.org/~joestein/kafka-0.7.1-incubating-docs/.
These are not very complete, we will try our best to publish 0.8 APIs
clearly. For Java examples, you can look at examples/ directory. Both
clients exist in the main kafka jar.

Thanks,
Neha
