Re: [jira] Created: (ZOOKEEPER-1009) BookKeeper as a sequencer
Hi Suranjan, Thanks for offering to contribute. Let me first point out  
that this is a feature for BookKeeper, a contrib project of ZooKeeper,  
and it is not about ZooKeeper directly. If you are interested in  
contributing to the ZooKeeper code base, then this one might not be a  
good pick.

About the feature, it is still in a design stage for me. I have some  
preliminary ideas, but I don't have a concrete plan yet. If you have  
ideas and you're willing to discuss them, please post them to the jira  
directly.

Thanks,
-Flavio
