Subject [jira] [Commented] (PHOENIX-1580) Support UNION ALL
Date Thu, 02 Apr 2015 20:10:57 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-1580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14393292#comment-14393292

Alicia Ying Shu commented on PHOENIX-1580:
------------------------------------------

[~jamestaylor] iterators.explain(steps) shows different plan steps than explain by looping
through plans. It shows plan steps at thread level I think. There will be a lot of repeated
information. For example: select * from t1 union all select * from t2; instead of showing
"Union All 2 queries", it will show " Union All 8 queries". So we should keep looping plans
in UnionPlan.explain().
