Debouncing #894

Thanks & Kudos
Huge thanks to the River team for crafting such a versatile job-processing engine!

What is debouncing?
Debouncing batches a rapid sequence of events into a single action after a specified “quiet” interval—only the final event in a burst triggers processing.

High-level use case
In a conversational system, users often send multiple messages in quick succession. We want to defer work until the conversation pauses, then invoke our chatbot once with the latest context. Is it possible to implement this with river?
