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: http://docs.confluent.io/2.0.1/clients/librdkafka/index.html /Magnus 2016-04-06 16:16 GMT+02:00 Vince Deters <vince.det...@sas.com>: > Hello, we have a requirement to run redundant Kafka consumers that consume > an identical stream of messages in identical order.
