Subject: Impact of old data on performance
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Hi All,

We are running a 3-node cluster with Cassandra 0.6.13.
We are in the process of upgrading to 1.x, but can't do so for a while 
because we can't take the cluster offline.
Until now 0.6.13 has run without problems, but lately we are getting 
some performance issues.
We are getting timeouts on both reads and writes.
The cluster contains a lot of "old" data which is only read very 
occasionally and not written to at all.
Is it possible for this data to negatively impact the performance of the 
cluster?
If so, would it help to move this data to another columnfamily/keyspace?

Cheers,

Stefan
