i have done no deletes, just inserts. so you are correct, there isn't any "data" to cleanup. however when i run some of the cleanup and/or compaction tasks the space used on disk actually grows, and i would like to force any unneeded files to be removed. as i write this, jonathan has responded with i believe what i need.

thx!

Are you deleting data through the API or just doing a bunch of inserts
and then running a compaction?  The latter will not result in anything
to clean up since data must be explicitly deleted.

my approach is this:

after only doing "puts" to cassandra for a while i stop my client and want
to perform the proper "cleanup" and/or "compact" operations that will reduce
the disk space used to a minimum.  however i can't seem to figure it out.
 i've done "major compaction", "cleanup", etc. but doesn't seem to get the
job done

so two questions

- what procedure is suggested to get rid of all unnecessary data?
- and what does the following "Compacted" file mean?  seams like it is
marking "88" as compacted, but there are no more compactions happening
according to compaction mgr
