Subject [jira] [Created] (CASSANDRA-6917) enum data type
Date Mon, 24 Mar 2014 19:22:45 GMT
Benedict created CASSANDRA-6917:
-----------------------------------

             Summary: enum data type
                 Key: CASSANDRA-6917
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6917
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Benedict
            Priority: Minor


It seems like it would be useful to support an enum data type, that automatically converts
string data from the user into a fixed-width data type with guaranteed uniqueness across the
cluster. This data would be replicated to all nodes for lookup, but ideally would use only
the keyspace RF to determine nodes for coordinating quorum writes/consistency.

This would not only permit improved local disk and inter-node network IO for symbology information
(e.g. stock tickers, ISINs, etc), but also potentially for column identifiers also, which
are currently stored as their full string representation.

It should be possible then with later updates to propagate the enum map (lazily) to clients
through the native protocol, reducing network IO further.
