[jira] [Created] (CASSANDRA-5502) Secondary Index Storage

Brooke Bryan created CASSANDRA-5502:
---------------------------------------

             Summary: Secondary Index Storage
                 Key: CASSANDRA-5502
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5502
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Brooke Bryan


Currently, both the CF data, and the secondary index data are stored within the same folder on disk.  Being able to split these into separate folders could be a great improvement with performance.  With our data, and secondary index, we will query the index a lot more, so can optimise hardware for the two traffic shapes coming through.

Something like /Keyspace/CF/indexes/indexname/*.db

Not too sure how much would be involved to change this, but I would imagine fairly cheap cost to reward.
