Appy commented on HBASE-14777:
------------------------------
On side note (looking the code around this patch made me realize this), in
IntegrationTestReplication we run internally, with 200 million rows, we were
seeing significant GC pressure on the sink side. GC pauses were 10-30 sec long,
no doubt the tests were failing (heap size = 4G).
Reason being, KeyValues are living long enough to be promoted to old
generation. All KeyValues are kept around until every last one is replicated.
Next, we can probably optimize that, it will significantly reduce gc pressure
in sink clusters.
