developthou commented on CASSANDRA-10898:
-----------------------------------------
I wanted to try this but I am running into the following error
{code:java}
ALTER TABLE mytable1 with compaction = {'class' : 'SizeTieredCompaction',
'exceptions' : { 10.1.1.1 : {'class' : 'TimeWindowCompactionStrategy'} } };
SyntaxException: line 1:103 no viable alternative at input '.'
(...'SizeTieredCompaction', 'exceptions' : { 10.1[.]...){code}
I am not able to find any documentation. Can you please help?
I am in Cassandra

> Migrate Compaction Strategy Node by Node

> Key: CASSANDRA-10898
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10898
> Project: Cassandra
> Issue Type: Improvement
> Components: Legacy/Tools, Local/Compaction
> Reporter: Andrew From
> Priority: Normal

> It would be a great feature to be able to slowly change the compaction
> strategy of a ColumnFamily node-by-node instead of cluster wide. Currently if
> you change it cluster wide there's no good way to predict how long it will
> take. Thus the process could run for days while you still need the live data,
> but the cluster responds much more slowly due to the compaction strategy
> migration.
> I stumbled across
> http://blog.alteroot.org/articles/2015-04-20/change-cassandra-compaction-strategy-on-production-cluster.html
> which gave me the idea. I was thinking this would be a nice feature to add
> to NodeTool, provided that the strategy in the blog is sound I wouldn't mind
> going ahead with the dev work to automate it. If not I would love to hear
> other ideas on how to best make this happen.
