Implement Task Queues with Redis Streams
The lesson shows how Streams provide an append-only durable task queue using XADD to write messages, XReadGroup to consume them, and XACK to acknowledge processing. It covers FIFO semantics, guaranteed delivery, dead letter queues with XCLAIM and XPENDING, timeout handling, and how to choose between the broadcast Pub/Sub model and the coordinated Streams pipeline for AI workloads.
