Not only it won't be trivial, but I don't have it completely clear that if
we separate Zab and ZooKeeper you will have exactly what you need. In our
previous discussions about this issue, we ended up concluding that we would
need a richer interface than simply abcast and abdeliver. For example, one
important aspect currently is stable storage for logging and checkpointing.
To separate the ZooKeeper application and Zab we would have to decide which
side would manage it, but both sides would need access to to it some way.
It sounds like a good idea to think carefully if a separate Zab would
really satisfy your requirements before spending time on the
implementation.

I will try take a look at the patch of jira

It's non-trivial - but iirc the patches/links on ZOOKEEPER-30 show the
finished work product from the original effort. I suspect that this
would be a great starting point, most of the work being to "port"
those changes onto the latest trunk. Ben what do you think? Was the
original approach solid? Seems like a great starting point.

Sure, I am interested in. What should I do besides reading the papers,
downloading the code compiling and doing some code walkthrough ?
Tks,

it's funny, i was just thinking about this yesterday.
no one is working on it, so it is still open.
it is a non-trivial piece of work, but i'd be willing to give guidance
if
you are interested in it.

Hi,
I need to implement a replication protocol and therefore I need total
order
broadcast primitive. I was thinking of using Zab. But I saw that the
broadcast protocol is very intermixed with Zookeeper's tree. I heard
of
ZOOKEEPER-30 . What happen of it ? It still open. If code contribution
is
still needed I would be glad to do it if someone could mentor me on
the
task.
Thanks,
André Oriani
