Jay Kreps commented on KAFKA-2045:
----------------------------------
Okay so since most the discussion here is on optimizing memory allocation let's
use this ticket for that.
I filed KAFKA-2063 to cover bounding the fetch response size. I think that is a
prerequisite for this ticket and also a bigger problem (those big allocations
actually often cause OOM).
> Memory Management on the consumer

> We need to add the memory management on the new consumer like we did in the
> new producer. This would probably include:
> 1. byte buffer re-usage for fetch response partition data.
> 2. byte buffer re-usage for on-the-fly de-compression.
