Subject Re: Kafka C/C++ client with consumer group support?
Date Wed, 06 Apr 2016 16:04:47 GMT
Hi Vince,

librdkafka (master branch) supports >=0.9 balanced consumers groups:
https://github.com/edenhill/librdkafka

As long as you are using different consumer groups each group will receive
the same set of messages.


Example C++ consumer:
https://github.com/edenhill/librdkafka/blob/master/examples/rdkafka_consumer_example.cpp#L398

API docs:
