Subject [jira] Commented: (CASSANDRA-1186) futureproof [KS|CF]MetaData
Date Sun, 13 Jun 2010 05:06:13 GMT


Jeff Hammerbacher commented on CASSANDRA-1186:

I feel comfortable saying that the serialization format for Avro will not change again in
the 1.x series, and the object file container almost certainly will not change.

> KSMetaData/CFMetaData serialization is fragile.  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.
