I have never written any code that uses threads.
I have a web application that accepts a POST request, and creates an image based on the data in the body of the request.
Would I want to spin off a thread for the image creation, as to prevent the server from hanging until the image is created? Is this an appropriate use, or merely a solution looking for a problem ?
Please correct any misunderstandings I may have.
Usual approach for handling HTTP requests synchronously is to spawn (or re-use one in the pool) new thread for each request as soon as it comes.
However, python threads are not very good for HTTP, due to GIL and some i/o and other calls blocking whole app, including other threads.
You should look into multiprocessing module for this usage. Spawn some worker processes, and then pass requests to them to process.
