Enis Soztutar commented on HBASE-7162:
--------------------------------------
bq. Turns out that (in our scenario) 60% of the time was spent is just
allocating ByteBuffer to back the decoded KeyValues where it would have been
sufficient to just create a KV interface that points to an existing buffer for
the key and existing buffer for the value.
Does 60% include just the allocation, or allocation + deserialization/copy. I
was also thinking along the lines of keeping just the pointers to the block
cache for KV's, and only deserializing them to the socket buffers.
