Germán Blanco commented on ZOOKEEPER-102:
-----------------------------------------
Avro seems to have a better support for modifying the message and adding
optional elements without breaking backwards compatibility. I think that would
be nice to have.
But of course, changing to Avro (or anything else) would mean breaking the
upgrade between two releases. So it is not an easy decision.
> Need to replace Jute with supported code

> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-102
> Project: ZooKeeper
> Issue Type: Improvement
> Reporter: Benjamin Reed
>
> ZooKeeper currently uses Jute to serialize objects to put on the wire and on
> disk. We pulled Jute out of Hadoop and added a C binding. Both versions of
> Jute have evolved (although Hadoop still doesn't have a C binding). It would
> be nice to use a more standard serialization library. Some options include
> Thrift or Google's protocol buffers.
> Our main requirements would be Java and C bindings and good performance. (For
> example, serializing to XML would give us incredibly bad performance and
> would not be acceptible!)
