----------------------------------
Resolution: Won't Fix
> provide a bookie store interface.
> ---------------------------------

> Key: BOOKKEEPER-566
> URL: https://issues.apache.org/jira/browse/BOOKKEEPER-566
> Project: Bookkeeper
> Issue Type: Improvement
> Components: bookkeeper-server
> Reporter: Sijie Guo
>
> Currently, Bookie does a lot of things, managing storage, managing bookie
> state (readonly or shutdown), handling zookeeper connections. It would be
> better to put SyncThread, Journal and LedgerStorage under a bookie store
> interface. so bookie just interacts with BookieStore for storage, interacts
> with ZooKeeper for membership management and manage the state transition
> through a StateTransitor (turn to readonly or shutdown).
> A BookieStore interface is easy to evaluate storage performance itself, and
> easy for plugging different storage implementation in future.
