Subject [jira] [Commented] (HBASE-6666) Allow RegionObserver to access other regions on the same server.
Date Sat, 29 Dec 2012 11:34:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6666?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13540864#comment-13540864

Anoop Sam John commented on HBASE-6666:

Within a RegionObserver we can access any other region in that RS via the HRegionServer#getOnlineRegion

Or you mean some thing else here?

> This is an idea I had some time back. It would be nice if a RegionObserver (or Endpoint)
could get access to all other regions on the same RegionServer to efficiently make updates
to those regions as well (instead of going through the standard HTable path).
> Together with a smart region placement strategy this can lead to much better performance
for some coprocessor tasks.
> Maybe it could be abstracted in a special HTable implementation.
