stack commented on HBASE-3247:
------------------------------

@Steven Yes, we should start with RowLog 
(http://www.lilyproject.org/maven-site/0.1/apidocs/org/lilycms/rowlog/api/RowLog.html).

bq. I'm wondering, as I'm seeing a proliferation of alternative yet overlapping 
approaches to a certain number of issues (secondary indexes, change listening) 
which in the end could confuse new users.

-1 to proliferation of alternate yet overlapping... things

What you fellas suggest for bootstrapping system -- doing a fat bulk load into 
the search index -- and then cutting over to rowlog for incremental updates?  
Doesn't there have to exact transition so followers do not miss edits?  You 
fellas have ideas for how to do that?

> 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.
