Subject [ANNOUNCE] storm-cassandra 0.4.0-rc2
Date Wed, 21 Aug 2013 23:46:57 GMT
I'm pleased to announce the release of storm-cassandra 0.4.0-rc2.

Changes in this release:

The CassandraMapState implementation now uses row keys instead of column keys to improve performance
(Thanks @sorenmacbeth)
The CassandraMapState implementation now defaults to using the RING_DESCRIBE for node discovery
(Thanks @sorenmacbeth)
Added CassandraQuery state query implementation.
Added support for multiple keyspaces per function/state (NOTE: This is an API/configuration
change -- TupleMappers must now implement the mapToKeyspace() method)
CassandraMapState now supports TTL to allow old state data to be cleaned up/deleted automatically.
CassandraState now supports configurable maximum batch mutation size.
RING_DESCRIBE is now the default node discovery method.

Artifacts should be available in maven central in a few hours.

Questions/feedback welcome.
