Subject Re: regarding space taken by different column families in Cassandra
Date Wed, 09 Feb 2011 09:49:25 GMT
After 1 hour ,from the application was done, the size of data folder become
14 GB and the result of cfstats is matching with this number (and Space used
(live) become equal to Space used (total) ).

CF1-    Space used (live)  :    7196278850
               Space used (total):     7196278850
CF2-       Space used (live)  :    2458866899

               Space used (total):     2458866899

CF3-       Space used (live)  :    2871096369

               Space used (total) :    2967445550

CF4-       Space used (live)  :    1536044466
               Space used (total) :    1536044466

After the application was done what kind operation was going on in Cassandra
and how much space it would require ?

regards,
abhinav
