[jira] Commented: (CASSANDRA-1308) Switch Migrations Serialization to Avro

["Stu Hood (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-1308?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12892534#action_12892534 ] 

Stu Hood commented on CASSANDRA-1308:
-------------------------------------

Shoot. It's already looking like the decision to re-use the KsDef and CfDef from the public interface was a bad idea: this ticket will involve adding a lot of records that we don't want in the public API:
* (Add|Drop|Rename)ColumnFamily
* (Add|Drop|Rename)Keyspace
* A named union/record that can contain any of those records

Since Avro protocols can't refer to records/schemas defined in other protocols, these objects must be defined in the same protocol as some private KsDef/CfDef objects.

> Since the Migrations framework is new in 0.7, it would be nice to finalize its serialization before anything goes out the door.
