Kafka C/C++ client with consumer group support?

[Vince Deters]

Hello, we have a requirement to run redundant Kafka consumers that consume an 
identical stream of messages in identical order. For this reason we plan to 
have these consumers consume from the same topic partition and identify 
themselves as unique consumer groups. Does any C/C++ Kafka client have this 
kind of consumer group support built in? Thanks,
Vince
