Raul Gutierrez Segales commented on ZOOKEEPER-102:
--------------------------------------------------
We don't necessarily have to break other clients. Can't we not use the protocol
field in the ConnectRequest to negotiate such things as serialization (or
compression, etc... it's a 32bit after all, lots of space!)?

> Key: ZOOKEEPER-102
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-102
> Project: ZooKeeper
> Issue Type: Improvement
> Reporter: Benjamin Reed
> Fix For: 4.0.0
>
>
> 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!)
