Lars Hofhansl commented on HBASE-7162:
--------------------------------------
The Cell stuff is a cool step into the right direction.
We just came across this today again when profiling scanning when FastDiff is
enabled.
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.
