Benedict commented on CASSANDRA-6726:
-------------------------------------
[~jbellis] I'd be inclined to include this patch in 2.1.1, otherwise we're
unlikely to see much benefit from it, as I fully expect the new file format to
not use these classes at all (and maybe not even the old format in 3.0, if we
deliver an in process page cache)
> Recycle CompressedRandomAccessReader/RandomAccessReader buffers independently
> of their owners, and move them off-heap when possible

> Whilst CRAR and RAR are pooled, we could and probably should pool the buffers
> independently, so that they are not tied to a specific sstable. It may be
> possible to move the RAR buffer off-heap, and the CRAR sometimes (e.g. Snappy
> may possibly support off-heap buffers)
