Subject [jira] [Commented] (ACCUMULO-212) Add coprocessors to Accumulo
Date Thu, 02 May 2013 21:50:17 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13647937#comment-13647937

Adam Fuchs commented on ACCUMULO-212:
-------------------------------------

I agree with Keith -- the concept of "coprocessors" has been defined in many ways by different
groups. HBase coprocessors don't really look much like Bigtable coprocessors, which are not
really well defined in the literature anyway. The thing that we really need in Accumulo is
a mechanism that safely do triggered operations outside of "the current row" without introducing
the possibility of a deadlock. Hooks don't count as "coprocessors" IMO.
