Subject [jira] Commented: (CASSANDRA-2069) Read repair causes tremendous GC pressure
Date Fri, 28 Jan 2011 16:17:43 GMT


Jonathan Ellis commented on CASSANDRA-2069:

In the log snippets I saw the heap was legitimately nearly-full during the repair process.
 What does MAT show is using all the memory?

Take one down, delete its data, then bring it back up and issue 1M reads against it.  After
the run is done you will see at least 1 STW long enough to mark the node as dead, often 4
or 5.
