There are ways to dynamically update the cluster membership today,
granted while they are dynamic they are not dynamic in the sense of 107:

107 is still pending. Henry was interested to implement this, I'm not
sure his current status. Henry? I think this is a
Hi -
Yes, I'm still interested in this JIRA but it's a significant change to ZK
which would be best suited for probably the 4.0 release. I have a rough
implementation that 'works' but still leaves some issues unresolved. I don't
have a great deal of time for this issue at the moment though, which
FYI, Ben has been working on Netty integration with ZooKeeper. One of
the benefits of this is it provides encryption and certificate based
connection auth - which would be a great way (cert) to solve some of the
security issues highlighted in 107. So the pieces are there, interest is

Thanks to all of you that responded. This feature is also important to the
project I am working on. Although we would have to find someone with the
right skills to contribute to it.
Henry, Do you have an estimate on how long this task would take if someone
were to start with your prototype?

It's very difficult to say how long this would take. There are a number of
issues that need to be resolved by design rather than code. For example, the
question of finding the cluster when the membership has changed is
unanswered.
The changes to the core protocol will need substantial
I think it would be good to have a design document, just to reason
about it and make sure that the mechanism we are introducing is not
flawed. It is easy to get these things wrong.

Is this the right forum to ask this question or should I post an update to
the bug report?
Thanks
