10. Messaging...
Point-to-point vs pub-sub
● Queues for point to point messaging (1-1)
○ Single consumer for each message
○ Can be load balanced with multiple
consumers
● Topics for publish/subscribe (1-many)
○ Interested parties can subscribe to a single topic
○ Topics can be hierarchical
○ Durable and non-durable subscriptions
