Subject Re: merge sstables

I assume you are using the leveled compaction strategy because you have 5mb
sstables and 5mb is the default size for leveled compaction.

To change this default, you can run the following in the cassandra-cli:

update column family cf_name with compaction_strategy_options = {sstable_size_in_mb: 256};

To force the current sstables to be rewritten, I think you'll need to issue a
nodetool scrub on each node. Someone please correct me if I'm wrong on this.
