Description

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.
