The maximum number of messages that can be stored in a topic subscription.
If a new message arrives on subscriptions that have reached the specified limit, then the first-most available messages on these subscriptions will be deleted to make room for the new message. Subscription messages are immune from this deletion if they're participating in a pending transaction, have already been passed to a consumer and are awaiting acknowledgement, or if they are part of a Unit-of-Work that is still waiting to accumulate all of its messages. Note that if all messages are immune from deletion, then a new message can cause a subscription size to exceed its limit.
A value of -1 means no limit override.
