Perform Task Directly After Returning JSON

Perform Task Directly After Returning JSON

I need to perform a task whenever the mobile app requests certain data.
The user does not need the task performed right away, but may need it
within the next 2 minutes.
I am still fairly new to Python / web dev so I am not quite sure how to
accomplish this.
I don't want the user to wait for the task performed, it'll probably take
30 seconds, but I'd still it rather be 30 seconds faster.
Is there anyway that I can send a response, so that the user gets the
required info immediately, and then the task is performed right after
sending the JSON.
Is it possible to send a Response to the mobile app that asked for the
data without using return so that the method can continue to perform the
task the user does not need to wait for?
@app.route('/image/<image_id>/')
def images(image_id):
# get the resource (unnecessary code removed)
return Response(js, status=200, mimetype='application/json')
# once the JSON response is returned, do some action
# (what I would like to do somehow, but don't know how to get it to work



On second thought maybe I need to do this action somehow asynchronously so
it does not block the router (but it still needs to be done right after
returning the JSON)
