In business automation
A queue is suitable when work arrives in bursts or takes longer than a request can remain open. It enables controlled processing and tracking of waiting tasks.
Examples
These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.
Business process example
A website receives several files for processing and returns a request ID after storing them. Workers fetch tasks from the queue, process each file, and update its status when the result is ready.
Relevant tools
- n8n
- Queue mode is a specific operational option; workflows can also connect to an external queue service.
What to check
- Check when a message is marked complete and what happens if a worker fails midway. A queue does not guarantee that a message will not be delivered again.
