Subject [jira] [Commented] (CASSANDRA-2749) fine-grained control over data directories
Date Thu, 13 Oct 2011 20:43:14 GMT

Pavel Yaskevich commented on CASSANDRA-2749:
--------------------------------------------

Looks better now but I don't like how you changed DescriptorTest especially testLegacy() "userActionUtilsKey"
there is meant to be a CF name, so it seems like current version does not work correctly?

> 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."
