Subject about the compaction and read performance
Date Fri, 17 Feb 2012 07:14:13 GMT

Cassandra has no way of knowing that all the data is in the most recent sstable, and will
have to check the others too, and this bring a lot of difficulty to data compaction.

I have a question that if  I want a high performance data compaction, how can I implement
that all the columns are all in the most recent sstable, by this, I think the read and write
performace will be better.
