Add CassandraDataModel
----------------------
Key: MAHOUT-770
URL: https://issues.apache.org/jira/browse/MAHOUT-770
Project: Mahout
Issue Type: Improvement
Components: Collaborative Filtering
Affects Versions: 0.5
Reporter: Sean Owen
Assignee: Sean Owen
Priority: Minor
Fix For: 0.6
Attachments: MAHOUT-770.patch
In the spirit of MongoDBDataModel I'd like to add a CassandraDataModel as a
backing store for non-distributed recommenders.
It takes a somewhat different approach, heavily reliant on in-memory caching,
as Cassandra is a different beast.
Patch is attached. This goes in integration, not core. It uses Hector, not the
raw Thrift API.
