Re: [jira] Created: (ZOOKEEPER-1009) BookKeeper as a sequencer

[Flavio Junqueira]

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.

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. -- This message is automatically generated by JIRA.
