Subject [jira] [Commented] (PHOENIX-2478) Rows committed in transaction overlapping index creation are not populated
Date Thu, 21 Jan 2016 04:10:39 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-2478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15110005#comment-15110005

James Taylor commented on PHOENIX-2478:
---------------------------------------

Never mind, [~poornachandra]. We just do a single commit, so the change set would be over
the entire index table.

> The case that is failing is when a commit starts before an index exists, but commits
after the index build is completed. For transactional data, this is problematic because the
index gets a timestamp after the commit of the data table mutation and thus these mutations
won't be seen during the commit. Also, when the index is being built, the data hasn't yet
been committed and thus won't be part of the initial index build.
