i'm trying to draw some correlation between the size of my data and the
space used on disk. i have set <GCGraceSeconds>1</GCGraceSeconds> so
there isn't any reason to keep data around.
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
