Subject [jira] [Commented] (HBASE-7474) Endpoint Implementation to support Scans with Sorting of Rows based on column values(similar to "order by" clause of RDBMS)
Date Fri, 24 Apr 2015 00:33:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7474?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14510144#comment-14510144

Anil Gupta commented on HBASE-7474:
-----------------------------------

Really sorry for such a late reply. At the time i started writing this CP, Phoenix was not
there.  IMO, Phoenix is already providing this feature now and Phoenix has richer toolset
to do stuff like this.
However, if commiters think this would be a valuable feature in HBase. I will be happy to
resume work on this patch.

> Recently, i have developed an Endpoint which can sort the Results(rows) on the basis
of column values. This functionality is similar to "order by" clause of RDBMS. I will be submitting
this Patch for HBase0.94.3
> I am almost done with the initial development and testing of feature. But, i need to
write the JUnits for this. I will also try to make design doc.
> Thanks,
