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.
