Changes API: API for pulling edits from HBase
---------------------------------------------

                 Key: HBASE-3247
                 URL: https://issues.apache.org/jira/browse/HBASE-3247
             Project: HBase
          Issue Type: Task
            Reporter: stack


Talking to Shay from Elastic Search, he was asking where the Changes API is in HBase.  Talking
more -- there was a bit of beer involved so apologize up front -- he wants to be able to bootstrap
an index and thereafter ask HBase for changes since time t.  We thought he could tie into
the replication stream, but rather he wants to be able to pull rather than have it pushed
to him (in case he crashes, etc. so on recovery he can start pulling again from last good
edit received).  He could do the bootstrap with a Scan.  Thereafter, requests to pull from
hbase would pass a marker of some  sort.  HBase would then give out edits that came in after
this marker, in batches, along with an updated marker.
