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.
