Subject can I kill very old data files in my data folder (I know that sounds crazy but....)
Date Wed, 18 Jun 2014 17:56:35 GMT
I have a column family that only stores the last 5 days worth of some
data...and yet I have files in the data directory for this CF that are 3
weeks old.  They take the form:

keyspace-CFName-ic-nnnn-Filter.db
keyspace-CFName-ic-nnnn-Index.db
keyspace-CFName-ic-nnnn-Data.db
keyspace-CFName-ic-nnnn-Statistics.db
keyspace-CFName-ic-nnnn-TOC.txt
keyspace-CFName-ic-nnnn-Summary.db

I have six bunches of these file groups, each with a different nnnn
value...and with timestamps of each of the last five days...plus one group
from 3 weeks ago...which makes me wonder if that group  somehow should have
been deleted but were not.

The files are tens or hundreds of gigs so deleting would be good, unless
its really bad!

Thanks,

Brian Tarbox
