[jira] [Updated] (CASSANDRA-7666) Range-segmented sstables

["Jonathan Ellis (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-7666?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jonathan Ellis updated CASSANDRA-7666:
--------------------------------------

    Description: 
It would be useful to segment sstables by data range (not just token range as envisioned by CASSANDRA-6696).

The primary use case is to allow deleting those data ranges for "free" by dropping the sstables involved.  (We may also be able to leverage this information in compaction.)

Relational databases typically call this "partitioning" the table, but obviously we use that term already for something else: http://www.postgresql.org/docs/9.1/static/ddl-partitioning.html
