-----------------------------------------

If noone else has a plan to work on this, I would like to pick this one up to get familiarize with code base.

> In the new producer, when a partition has no leader for a long time (e.g., all replicas are down), the records for that partition will stay in the RecordAccumulator until the leader is available. This may cause the bufferpool to be full and the callback for the produced message to block for a long time.
