upgrade:
- |
In RabbitMQ, messages now have a TTL of 10 minutes and inactive queues will
expire after 1 hour. These queue arguments can be changed dynamically at
runtime [1], but it should be noted that applying a TTL to queues which
already have messages will discard the messages when specific events occur.
See [2] for more details. Note that the contents of the RabbitMQ
definitions.json are now changed, meaning RabbitMQ containers will be
restarted on next deploy/upgrade.
