Siyuan, Marc: We are currently working on topic-deletion supports (KAFKA-330<https://issues.apache.org/jira/browse/KAFKA-330>), would first-delete-then-recreate-with-fewer-partitions work for your cases? The reason why we are trying to avoid shrinking partition is that it would make the logic very complicated. For example, we need to think about within-partition ordering guarantee with partition merging and producing-in-progress simultaneously.
