Subject [jira] Created: (CASSANDRA-1437) Improve default handling/validation for config.Metadata objects
Date Thu, 26 Aug 2010 18:26:55 GMT
Improve default handling/validation for config.Metadata objects
---------------------------------------------------------------

                 Key: CASSANDRA-1437
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1437
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Stu Hood
            Priority: Minor
             Fix For: 0.7.0


Post CASSANDRA-1436, we'll be back to single Avro objects to describe schemas for client and
internal use: it would be a good opportunity to improve our handling of defaults and our validation
of config.*Metadata objects.

Right now, we have multiple ways to convert a CfDef to a CFMetaData object (for example),
due to the differences between the defaults that should be chosen for a _new_ column family
(when we receive the CfDef from a client), versus an _existing_ column family after a new
setting has been added (deserializing a CfDef from disk). Finding a unified way to handle
these two (potentially different) default values would be excellent.
