Subject [jira] Updated: (CASSANDRA-276) use subdirectory-per-table for data files
Date Thu, 16 Jul 2009 17:01:15 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-276?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arin Sarkissian updated CASSANDRA-276:
--------------------------------------

    Attachment: jbellis-comments.patch

Here's a patch with the comments from Jonathan Ellis.

There were zero usages for DD.getDataFileLocationForTable() so i renamed I renamed DD.getCompactionFileLocationForTable()
to DD.getDataFileLocationForTable()

Also removed DD.getDataFileLocation() because it was never used

re: the indexoutofbounds possibility in getDataFileLocationForTable():
the call to getAllDataFileLocationsForTable(table) essentially just loops over dataFileDirectories_
and appends the table name as you suggested.

structure for free.
