Subject [jira] Commented: (CASSANDRA-79) Multi-table support
Date Wed, 20 May 2009 03:16:49 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-79?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12710981#action_12710981
] 

Jonathan Ellis commented on CASSANDRA-79:
-----------------------------------------

Log entries are just Rows, right?  So adding table name there fixes that part.

the header stuff is a bit more complex.  (you mean CL.clHeader_ right?)  I don't think we
want to actually add fields there -- wouldn't just making the id generator global (so that
the id would still uniquely identify a CF in any table) instead of per-table solve the updateHeader
problem?

> 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.
