Subject is there a way to drain node(and prevent reads) and upgrade sstables offline?
Date Fri, 22 Feb 2013 17:01:08 GMT
We would like to take a node out of the ring and upgradesstables while it is not doing any
writes nor reads with the ring.  Is this possible?

I am thinking from the documentation

 1.  nodetool drain
 2.  ANYTHING to stop reads here????
 3.  Modify cassandra.yaml with compaction_throughput_mb_per_sec = 0 and multithreaded_compaction
= true temporarily
 4.  Restart cassandra and run nodetool upgradesstables keyspace CF
 5.  Modify cassandra.yaml to revert changes
 6.  Restart cassandra to join the cluster again.

Is this how it should be done?
