Hi

I made a simple webservice but when I test load test, it didnt work asyc.
What must I do for asyc

[csselo]

When you call synchronous web service the service processes the request and return HTTP status code 200 OK (1) if everything went as expected, or error 4xx. The call is blocked while processing and the request and can take significant time.

When web service is asynchronous the main difference is that call should return instantly with HTTP 202 ACCEPTED (2) which means that request is taken in queue but not processed yet.

@csselo for async web service service indeed needs to return HTTP 202 on call and then push result to client on completion, say using web sockets.

When a process take a long time, the other posts are waiting for it so it doesnt work async

[pavlov99]

Lets denote slow and fast methods/APIs as A and B. On client call of method A, server adds it to the execution queue and returns queue id of the task to client. At this point of time, server is free to accept other method B. Meanwhile, first task from the queue is taken by another process, which would push result to the client on completion. One of the ways to push result is to use web sockets.

is there any backend setting?

Hi

backend config?

[pavlov99]

@csselo no, as of now backend config for asyncio does not exist.

I think it needs backend setting
