Dean Hiller commented on CASSANDRA-5335:
----------------------------------------
We went to org.apache.cassandra.db -> ColumnFamilies -> {our keyspace}-> {our
CF} -> Attributes -> CompactionStrategyClass and then changed "SizeTiered" to
"Leveled" or rather the whole string was
org.apache.cassandra.db.compaction.LeveledCompactionStrategy. We hit
enter...nothing happened. We ran a "nodetool compact databus5 nreldata" and
the files are the same. unfortunately we are in QA with little data and wanted
to set the default size=1 but could not find that in JMX. We can't tell if it
is working or not.
> need ability to switch to LCS node by node

> Key: CASSANDRA-5335
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5335
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.2.2
> Environment: linux, cassandra 1.2.2
> Reporter: Dean Hiller
> Labels: compaction
>
> when we switched to LCS, nearly all the servers started rewriting their file
> structure. We need a way to switch just one node so we can slowly roll out a
> huge change like this. doing the whole cluster brought it to it's needs and
> we tried nodetool stop compaction on some nodes but that did not help at all.
> We had to really wait overnight for all LCS to finish.
> We had also tried nodetool setcompactionthroughput 1 which also had no effect
> and performance was still pretty bad. Ideally, none of this would be a
> problem if we were just doing one node as we would just pull the node back
> out while it was converting to LCS.
