> We will use this JIRA to track the list of issues to resolve to get a working new consumer client. The consumer client can work in phases -
> 1. Add new consumer APIs and configs
> 2. Refactor Sender. We will need to use some common APIs from Sender.java (https://issues.apache.org/jira/browse/KAFKA-1316)
> 3. Add metadata fetch and refresh functionality to the consumer (This will require https://issues.apache.org/jira/browse/KAFKA-1316)
> 4. Add functionality to support subscribe(TopicPartition...partitions). This will add SimpleConsumer functionality to the new consumer. This does not include any group management related work.
> 5. Add ability to commit offsets to Kafka. This will include adding functionality to the commit()/commitAsync()/committed() APIs. This still does not include any group management related work.
> 6. Add functionality to the offsetsBeforeTime() API.
> 7. Add consumer co-ordinator election to the server. This will only add a new module for the consumer co-ordinator, but not necessarily all the logic to do group management. 
> At this point, we will have a fully functional standalone consumer and a server side co-ordinator module. This will be a good time to start adding group management functionality to the server and consumer.
> 8. Add failure detection capability to the consumer when group management is used. This will not include any rebalancing logic, just the ability to detect failures using session.timeout.ms.
> 9. Add rebalancing logic to the server and consumer. This will be a tricky and potentially large change since it will involve implementing the group management protocol.
> 10. Add system tests for the new consumer
> 11. Add metrics 
> 12. Convert mirror maker to use the new consumer.
> 13. Convert perf test to use the new consumer
> 14. Performance testing and analysis.
> 15. Review and fine tune log4j logging
