Subject [jira] [Commented] (CASSANDRA-10070) Automatic repair scheduling
Date Mon, 07 Dec 2015 17:59:11 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15045350#comment-15045350

Jim Meyer commented on CASSANDRA-10070:
---------------------------------------

I think this is part of the motivation for building repair scheduling into Cassandra.  When
we write an external repair scheduler, it has no idea what the state of the cluster is, so
it just blindly issues repairs based on a time schedule.

> Scheduling and running repairs in a Cassandra cluster is most often a required task,
but this can both be hard for new users and it also requires a bit of manual configuration.
There are good tools out there that can be used to simplify things, but wouldn't this be a
good feature to have inside of Cassandra? To automatically schedule and run repairs, so that
when you start up your cluster it basically maintains itself in terms of normal anti-entropy,
with the possibility for manual configuration.
