messageRetentionDuration property
How long to retain unacknowledged messages in the subscription's backlog, from the moment a message is published.
If retain_acked_messages is true, then this also configures the
retention of acknowledged messages, and thus configures how far back in
time a Seek can be done. Defaults to 7 days. Cannot be more than 7 days
or less than 10 minutes.
Optional.
