Subject [jira] [Commented] (CASSANDRA-7232) Enable live replay of commit logs
Date Sat, 02 Aug 2014 14:27:12 GMT


Lyuben Todorov commented on CASSANDRA-7232:

I'll continue work on the assumption that the nodetool command will require a list of directories
that contain commit logs that need to be replayed, and a another param which will be the point-in-time
from which we should start restoring the CLs in the various directories.

> Replaying commit logs takes a restart but restoring sstables can be an online operation
with refresh. In order to restore a point-in-time without a restart, the node needs to live
replay the commit logs from JMX and a nodetool command.
