Andrew Purtell commented on HBASE-7055:
---------------------------------------
bq. CompactionConfiguration is base compaction config, it is not just
xml-based, it uses runtime store-specific settings. TierBased one adds more on
top of that; it seems that Tier-stuff doesn't belong to the main
CompactionConfiguration; and main CompactionConfiguration is not as simple as
generic Configuration. It's also Store (e.g. region/cf) specific.
Up to now we've had two distinct and cleanly separable configuration
mechanisms. The heavyweight Configuration which carries global, and currently
static configuration, and the table and column descriptors that can be CF
specific by definition and updated at runtime without requiring a process
restart. Pardon if I've misunderstood but mixing these would blur static and
dynamic configuration and that doesn't seem a good design option.
> port HBASE-6371 tier-based compaction from 0.89-fb to trunk - first slice
> (not configurable by cf or dynamically)
