Sergey Shelukhin commented on HBASE-7236:
-----------------------------------------

Yeah, versions and TTL are kind of a gray area. 
Stuff like compression and caching would be a better example for 2b.

> Regardless of the compaction policy, it makes sense to have separate configuration for
compactions for different tables and column families, as their access patterns and workloads
can be different. In particular, for tiered compactions that are being ported from 0.89-fb
branch it is necessary to have, to use it properly.
> We might want to add support for compaction configuration via metadata on table/cf.
