> The current MessageStore interface forces MessageStore implementations to allow for queries/deletes
based on semantic properties of records.  While some query like functionality is required
for the period of recovery after restart, querying the store is not required in normal operation.
  Delete operations (such as dequeuing messages) currently only supply the semantic keys (queue-id,
message-id) rather than allowing the store to provide the broker with a reference which can
be used for later efficient deletion.
