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

Just have one more PR for this (implementing the additional partitioner). Then 
we can close it.

> Currently the default partitioner uses a round-robin strategy to partition 
> non-keyed values. The idea is to implement a "sticky partitioner" that 
> chooses a partition for a topic and sends all records to that partition until 
> the batch is sent. Then a new partition is chosen. This new partitioner will 
> increase batching and decrease latency.
