Subject [jira] Commented: (CASSANDRA-79) Multi-table support
Date Tue, 19 May 2009 15:50:46 GMT


Jun Rao commented on CASSANDRA-79:

We need to think a bit more about CommitLog. Do we create a log file per table or do we have
a log file for all tables? The latter seems to make more sense. However, the CommitLog Header
has a couple of fields per CF. This needs to be expanded to per CF per table.

> Cassandra has preliminary support for multiple tables (namespaces / sets of ColumnFamilies)
but a lot of the code assumes there is only one.  Multitable support is important for allowing
multiple applications to run on a single cluster.  It's also useful to cleanly separate "system"
columnfamilies from application data.
