["Jaakko Laine (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-721?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jaakko Laine updated CASSANDRA-721:
-----------------------------------

    Attachment: 721-atomic_mod.patch

Adds atomic_mod command, which can be used to modify column/supercolumn value atomically. Requires ZooKeeper for locking. ZooKeeper is not required for those who do not use atomic_mod operation, since ZK connection is not created until atomic_mod is first used.
