org.apache.hedwig.server.persistence.PersistenceManager
An implementation of this interface will persist messages in order and assign a seqId to each persisted message. SeqId need not be a single number in general. SeqId is opaque to all layers above {@link PersistenceManager}. Only the {@link PersistenceManager} needs to understand the format of the seqIdand maintain it in such a way that there is a total order on the seqIds of a topic.
