Delayed Message Processing with Redis Streams - RedisConf 2020

Delayed message processing can be valuable in many business processes. The problem of processing dynamically assigned delays is much more difficult than processing messages in a static processing window. We can scale this architecture easily—if the queue depth is too much for the current number of workers to deplete in the given window, we can simply add more workers. We can use any number of COTS products to implement this type of competitively processed workload in a static processing window.

Great Work! If it could be shown with Live Demo with short windows for delayed processing it will be very much easier to understand. I had to rewind and replay on demo to understand it better.
But kudos to Redis team for understanding that there might be need for Delayed processing in this real-time event processing world. :-)
