Subject [jira] [Commented] (HBASE-15879) Introduce Key interface
Date Mon, 20 Jun 2016 07:52:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15339119#comment-15339119

Anoop Sam John commented on HBASE-15879:
----------------------------------------

This comes under discussion of another issue as well. Now we have many optional interfaces
around Cell and most of the Cell impls implement those all.
SettableSeqid, SettableTimestamp, Streamable etc.   Most of these needed in server side only.
Was thinking of having single Cell extension ServerCell.  I think InternalCell is also good..
  I will work on this IA as that is needed in HBASE-15721

> Introduce an interface called Key and allow Cell implementations to implement this Key
interface for cases like KeyValue, OffheapKeyValue and DBE cells (Except prefix tree) so that
we can avoid copies when we deal with only Cells in case of block index creations (like ROOT,
Bloom etc). Helps in reduction of garbage also.
