Stu Hood updated CASSANDRA-1186: -------------------------------- Attachment: 0004-Add-utility-functions-for-dealing-with-Avro-serializ.patch 0005-Sync-up-Avro-schema-with-Thrift-and-add-CfDef.id.patch 0006-Replace-serialization-code-in-KS-CF-CMetaData-and-po.patch Rebased for trunk, and applied the following changes: * Removed the 'private' Avro schema that was in pre-0002: left behind the build.xml generalization ** Instead, serialization of config.KS/CF/CMetaData uses avro.Ks/Cf/ColumnDef * Switched back to a 'column per keyspace' datamodel in the "Schema" cf, with a magic column name to store the Avro schema * Squashed pre-0005 and pre-0006 to 0006 * Removed pre-0007 Ready for another look.

We need to be able to add > fields easily without breaking when we read old-style serialized bytes. > Avro and Thrift are designed to handle this. We should probably use one of > those rather than re-inventing the wheel. If Avro is mature enough for this > then let's use that, otherwise let's use Thrift. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
