We're using 0.82 beta and a homegrown c++ async library based on boost asio that has support for the offset api. (apikeys OffsetCommitRequest = 8, OffsetFetchRequest = 9, ConsumerMetadataRequest = 10)
If we use a java client and commit an offset then the consumer group shows up in the response from ConsumerMetadataRequest. However I cant figure out how to create a new one using the Kafka API. Also, my __consumer_offsets topic shows up with a replication factor of 1. Is that changeable? thanks, svante
