Symfony back ground activity after to send response error session

I'm using Symfony 4.4 with Redis for the session.

I have some controllers and I wish to update the DB on back ground after to send a reply to user.

So I have written a code like this:

class GetCatController extends AbstractController
{
    public function getCatController(LoggerInterface $logger, ManagerRegistry $doctrine, SessionInterface $session, ValidatorInterface $validator)
    {
       [...]
       $replyToSend =  new JsonResponse($reply, 200);
       $replyToSend->send();
       
      //My back ground activity like to do some query on the db.
        [...]

        return null;
    }

But I have some problems about the sessions.

Is there a better way to create and run background activity sending before the reply to user?

symfony redis php

There are two decent ways to do this.

If you are running PHP under php-fpm (not mod_php), you can dispatch & catch an event, kernel.terminate In Symfony pre-4.4, this is called PostResponseEvent (TerminateEvent from 4.4/5.0).

The better choice may be with Symfony Messenger. Here, you would create a message object, with all the information needed to perform the task, and send it to a background queue (Redis is supported as a queue). A worker then consumes that message, and does the task.
