> For regular topics, the slow consumer problem has a few solutions via the [discarding
policies|http://activemq.apache.org/slow-consumer-handling.html]
> For Virtual Topics, message expiry is the only viable option, however dispatch will be
blocked till expiry kicks in. In the same way that we can discard some messages for a slow
topic subscriber it can make sense to discard messages for a subscriber queue that is full
such that dispatch to fast queues can continue.
