Hello Everyone
is there any way to extend ZooKeeper data structure without breaking the
backward compatibility.
Suppose I want to add cuser field in StatPersisted
class StatPersisted {
........
ustring cuser; //user who create the node
}
This is fine with fresh ZooKeeper server installation, where ZooKeeper data is
created freshly
But this causes problem while de-serializing when server is new but points to
old ZooKeeper data.
Here by ZooKeeper data I mean snapshot and transaction log
In protocol buffers a field can be optional but in jute optional field is not
supported.
is there any way to overcome this jute limitation? any work around?
Best Regards
