Subject [jira] [Commented] (PHOENIX-3811) Do not disable index on write failure by default
Date Wed, 17 May 2017 23:57:04 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-3811?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16014955#comment-16014955

Andrew Purtell commented on PHOENIX-3811:
-----------------------------------------

This is not the kind of change that should go into a minor release. Deploy 4.10, develop your
app using secondary indexes, now update to 4.11 and a really important semantic has totally
changed. Shall we start Phoenix 5 in earnest?

> We should provide a way to configure the system so that the server takes no specific
action when an index write fails. Since we always throw the write failure back to the client,
the client can often deal with failures more easily than the server since they have the batch
of mutations in memory. Often times, allowing access to an index that may be one batch behind
the data table is better than disabling it given the negative performance that will occur
while the index cannot be written to.
