Hi Sachin,

You should choose a Task Queue in Mendix when you need to process background tasks reliably, in parallel, and in a scalable way, especially when task execution may be delayed or distributed. Unlike asynchronous microflow calls—which are immediate and tied to the user session—a Task Queue runs in the background and is decoupled from the user experience, making it ideal for heavy or long-running operations like sending emails, generating reports, or calling external APIs. Compared to scheduled events, which run at fixed times and are not designed for handling large volumes of dynamic tasks, Task Queues offer more flexibility by allowing you to enqueue tasks at runtime based on specific triggers. They also support concurrency control, retry logic, and queue prioritization, which gives you better control over system resources and error handling. Use Task Queues when you need scalable, fault-tolerant, and asynchronous execution of business logic without impacting the performance or responsiveness of your app’s front end.

Hope it helps!
