Subject [jira] [Resolved] (HBASE-6666) Allow RegionObserver to access other regions on the same server.
Date Wed, 09 Jan 2013 20:50:12 GMT

     [ https://issues.apache.org/jira/browse/HBASE-6666?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lars Hofhansl resolved HBASE-6666.
----------------------------------

    Resolution: Won't Fix

I was thinking something more abstracted straight into CoprocessorHost.HTableWrapper, but
what Anoop said is good enough. Closing.

> 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.
