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

> 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.
