Subject [jira] [Commented] (HBASE-9203) Secondary index support through coprocessors
Date Tue, 20 Aug 2013 13:46:54 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9203?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13744970#comment-13744970
] 

ramkrishna.s.vasudevan commented on HBASE-9203:
-----------------------------------------------

For the indexhalf store file reader,
Yes, as i said in the above comment 
bq.Mostly it will be the same data but the thing is we would read the HFile twice to create
the top and bottom files for the index region.
For the namespaces I think we could move index table to a namespace so that it is not directly
workable for the user something like a system table.
