Jonathan Ellis commented on CASSANDRA-5862:
-------------------------------------------
bq. My concern was the instance would be re-used across multiple sstables
therefore should be chosen per buffer. Is that not the case?
CRAR is always tied to a single SSTable.
bq. I was trying to future proof us switching back to crc or something but not
changing the post-compression. Think its safe to merge?
Yeah, if we do that we'll end up adding new version tests anyway. I think
YAGNI applies.

> Adler is significantly faster than CRC32:

> it checksums each mutation individually.)
