[jira] [Commented] (KAFKA-347) change number of partitions of a

Jay Kreps commented on KAFKA-347:
---------------------------------
This is more of a nice-to-have, no? Can't we postpone this beyond 0.8? Changing partition # will scramble the partitioning from the producer, and we don't really have this capability now.

Jun Rao commented on KAFKA-347:
-------------------------------
It can probably be pushed beyond 0.8. The only concern is that consumer parallelism is currently tied to # partitions.
