Broker persistence after a restart:

1. Behavior: persistence="false", All Unread messages are lost?

2. Behavior: persistence="true", Unread messages on persistence destinations (i.e., messages on queues and persistence topics) are restored?

Queue Depth:

1. Is there away to set queue depth (Max number of unread messages on a queue)?

DB Configuration:

1. The default db is Kaha? Does it need to be configured (spring entry)?

Example:

    <persistenceAdapter>
      <kahaPersistenceAdapter directory="activemq-data" maxDataFileLength="33554432"></kahaPersistenceAdapter>
    </persistenceAdapter>

Time-to-live TTL:

1. If there is no consumer on a JMS queue will a TTL messages expire. (be removed from the db)? issue

2. Is there a way to set TTL on a queue (Example: only keep one hours worth of messages in this queue)?
