Queues, publish/subscribe, and the log as a primitive. Delivery semantics, idempotency and ordering, then the architectures they make possible — and the debugging they cost you.

This module is 04.3 of the 5 in Messaging & Event Streams. It runs about 5 hours across 5 lessons, and closes with Replay — Rebuild a corrupted read model from the log alone, while new events keep arriving.
