Subject [jira] Commented: (CASSANDRA-406) SSTable File Metrics per CF
Date Wed, 02 Sep 2009 02:26:32 GMT


Sammy Yu commented on CASSANDRA-406:

For each CF, in the patch nodeprobe counts the number of sstables already by count the number
of keys returned in CFS.getSSTablesInfo.  We could add a specific method that just returns
count as it may make it easier for JMX clients.

Do we want to return the total size used in the data directory for each CF or does do we want
it globally for StorageService level?  I was thinking of adding one at the StorageService
level and it would just return the free space for each data directory.
