What is the difference between a task queue and a job scheduler?

A task queue is a data structure that holds tasks waiting to be processed, while a job scheduler manages when and how those tasks are executed.

Can you give me an example of each?

Sure! A task queue could be something like RabbitMQ, which holds messages to be processed. A job scheduler could be cron, which runs scripts at specified times.

When should I use a task queue instead of a job scheduler?

Use a task queue when you need to handle a large number of tasks asynchronously, and a job scheduler when you need to run tasks at specific times.

Are there any scenarios where both are used together?

Yes, in complex systems, a job scheduler can trigger tasks that are then placed in a task queue for processing, combining both functionalities.
