ramkrishna.s.vasudevan updated HBASE-13614:
-------------------------------------------
Attachment: HBASE-13614.patch
Removes the local KVOnlyKV in the HFileReaderImpl and EncodedSeeker. In all
these cases the scanner instances are per get or scan. So we could use the same
instance KeyOnlyKV to set the key part for comparisons in blockSeek or
seekToblock cases.
Also removes unused code in Prefixtree. With this and HBASE-13939 we avoid
cases where we create lot of KeyOnlyKeyValue in hot read path.
> Avoid temp KeyOnlyKeyValue temp objects creations in read hot path

> As part of HBASE-10800, move to new CellComparator, we are temp creating a
> Cell out of byte[]s so that the Comparator can compare. In read hot path, we
> can try minimize the object creations. The parent Jira added some such cases,
> which we can solve. This Jira will solve all such cases.
