Sergey Shelukhin commented on HBASE-7236:
-----------------------------------------
Details:
We want to do it in metadata as it makes logical sense; xml config usage would
split table/CF configuration into two places.
Given that the config for both current and tiered policy can be quite long, it
probably makes sense to make it nested, as opposed to a set of flat values
inside metadata.
I immediately start thinking of generic xml config override mechanism for
tables/cfs, but I am not sure this is necessary.
What do you think?
> add per-table/per-cf compaction configuration via metadata

> Project: HBase
> Issue Type: New Feature
> Components: Compaction
> Affects Versions: 0.96.0
> Reporter: Sergey Shelukhin
> Assignee: Sergey Shelukhin
>
> 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.
