Subject [jira] [Commented] (HBASE-10576) Custom load balancer to co-locate the regions of two tables which are having same split keys
Date Wed, 23 Apr 2014 04:51:18 GMT

ramkrishna.s.vasudevan commented on HBASE-10576:
------------------------------------------------

In the case of hindex we were trying to avoid direct scans on the index, but any way internal
scans may be needed. I think doing the above would mean that scans would not need to read
the META instead make the scan know which region to be scanned. That would mean it would be
change on how the scans work now.

> To support local indexing both user table and index table should have same split keys.
This issue to provide custom balancer to colocate the regions of two tables which are having
same split keys. 
> This helps in Phoenix as well.
