Chris Burroughs commented on CASSANDRA-2749: -------------------------------------------- It would also be cool (but this is obviously speculative) to have the ability to keep Index files on an SSD, and the larger data files on rotating disks. > fine-grained control over data directories > ------------------------------------------ > > Key: CASSANDRA-2749 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2749 > Project: Cassandra > Issue Type: New Feature > Components: Core > Reporter: Jonathan Ellis > Assignee: Pavel Yaskevich > Priority: Minor > Fix For: 1.0 > > > Currently Cassandra supports multiple data directories but no way to control > what sstables are placed where. Particularly for systems with mixed SSDs and > rotational disks, it would be nice to pin frequently accessed columnfamilies > to the SSDs. > Postgresql does this with tablespaces > (http://www.postgresql.org/docs/9.0/static/manage-ag-tablespaces.html) but we > should probably avoid using that name because of confusing similarity to > "keyspaces." -- This message is automatically generated by JIRA.
