Eshcar Hillel commented on HBASE-19095:
---------------------------------------
[~Apache9] can you please explain again why do we need the
{{preMemStoreCompaction(store)}} and the {{postMemStoreCompaction(store)}}
before and after {{doCompaction()}} ? What kind of manipulation do we want to
allow the user? Is it some preparation work before the compaction that cannot
be done in {{preMemStoreCompactionCompactScannerOpen(store)}}?, Is it something
equivalent to what is done on store file compaction?
> Add CP hooks in RegionObserver for in memory compaction
