Subject [jira] [Commented] (PHOENIX-2428) Disable writing to WAL on initial index population
Date Mon, 23 Nov 2015 20:06:11 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-2428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15022875#comment-15022875

Enis Soztutar commented on PHOENIX-2428:
----------------------------------------

If an RS fails in between, I don't think there is a reliable way to detect this and re-populate
the index. The flush() will still succeed, but there is no guarantee that you did not lose
any data even if flush succeeds.

> We should not be writing the WAL when we initially populate an index. Not only is this
obviously more efficient, but it also will prevent the writes from being replicated both of
which are good.
