QPID-5653: Open databases and upgrade on opening of configuration/message stores
> [Java Broker] Make message and configuration store stateless
> ------------------------------------------------------------
>
> Key: QPID-5653
> URL: https://issues.apache.org/jira/browse/QPID-5653
> Project: Qpid
> Issue Type: Improvement
> Components: Java Broker
> Reporter: Keith Wall
> Assignee: Keith Wall
>
> The MessageStore (and DurableConfigurationStore) implementations are
> currently stateful. They own the recovery process and have special rules
> around some states (in some states updates are ignored). This is overly
> complicated. Currently all store implementations need to code these rules.
> This is poor division of responsibilities and this presents a barrier to
> users wishing to produce their own store implementations.
> This change will simplify the responsibilities of the store:
> * introduce simpler lifecycle methods i.e. open/close
> * simpler state concept, the store is either open or not
> * visit methods for retrieving data from the store.
