Support mastered writes
-----------------------
Key: CASSANDRA-225
URL: https://issues.apache.org/jira/browse/CASSANDRA-225
Project: Cassandra
Issue Type: New Feature
Affects Versions: 0.4
Environment: all
Reporter: Sandeep Tata
Assignee: Sandeep Tata
Fix For: 0.4
Writes to a row today can be run on any of the replicas that own the row. An
additional set of APIs to perform "mastered" writes that funnel through a
primary is important if applications have some operations that require higher
consistency. Test-and-set is an example of one such operation that requires a
higher consistency guarantee.
To stay true to Cassandra's performance goals, this should be done in a way
that does not compromise performance for apps that can deal with lower
consistency and never use these APIs. That said, an app that mixes higher
consistency calls with lower consistency calls should be careful that they
don't operate on the same data.
