What is "worker" design pattern?

---

It could be that you are after a worker thread pattern, where you use a queue to schedule tasks that you want to be processed "offline" by a worker thread. Some solutions will use a pool of worker threads instead of single thread to achieve performance gains by utilising paralelisation.

Something like MapReduce comes to mind. Where multiple tasks can be performed in parallel on worker nodes.

Edit: As @larsmans mentioned, this is known as the Master/Worker pattern.
