Subject [jira] [Updated] (CASSANDRA-7666) Range-segmented sstables
Date Wed, 13 Aug 2014 16:34:19 GMT

     [ 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

Tokutek's take for mongodb: http://docs.tokutek.com/tokumx/tokumx-partitioned-collections.html
