Anoop Sam John commented on HBASE-15554:
----------------------------------------
bq.For the ROWCOL case we need one copy for creating the key[] with ROW and COL
and pass it to the hash.
So this is the main thing which allocates memory area right? The temp byte
arrays. So what we avoid here? No KeyValue object creation? Did not go
through the patch.
> StoreFile$Writer.appendGeneralBloomFilter generates extra KV
