[jira] Created: (ZOOKEEPER-1009) BookKeeper as a sequencer
BookKeeper as a sequencer
-------------------------
Key: ZOOKEEPER-1009
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1009
Project: ZooKeeper
Issue Type: New Feature
Components: contrib-bookkeeper
Reporter: Flavio Junqueira
Assignee: Flavio Junqueira
It would be interesting to use BookKeeper as a sequencer for a number of parallel streams of events. The general idea is to use BookKeeper to establish a total order on the events of concurrent streams, and use the ordered sequence as the input of an architectural element that processes the events in the streams. This way the state of the element is reproducible.
Given that we currently interleave the entries of concurrent ledgers in a bookie for writing efficiently, I believe it wouldn't be difficult to extend the interface to enable such a feature.

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

Hi Flavio,
Since long I have been wanting to contribute to ZooKeeper. Looking at the
this ticket, I am willing to start with it if given opportunity.
Could you please help me with it on how to go about this feature? (Is
someone else doing it?) What is process of contributing to ZooKeeper? How to
start?
Thanks,
