Subject [jira] [Commented] (PHOENIX-1580) Support UNION ALL
Date Sat, 14 Feb 2015 03:06:11 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-1580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14321191#comment-14321191

James Taylor commented on PHOENIX-1580:
---------------------------------------

ConcatResultIterator is not low level and will work fine. No need to implement your own iterator.
Just use the LookAheadResultIterator.wrap on each iterator. Look for examples in code and
follow Maryann's advice.

I'll do some research on the spec regarding order by and limit with union, though they'd work
fine. [~julianhyde] - any advice for us here?
