python - How to switch tasks between queues in Celery -


i've got couple of tasks in tasks.py in celery.

# should go 'math' queue  @app.task def add(x,y):     uuid = uuid.uuid4()     result = x + y     return {'id': uuid, 'result': result}  # should go 'info' queue @app.task def notification(calculation):     print repr(calculation) 

what i'd place each of these tasks in separate celery queue , assign number of workers on each queue.

the problem don't know of way place task 1 queue within code.

so instance when add task finishes execution need way place resulting python dictionary info queue futher processing. how should that?

thanks in advance.

edit -clarification-

as said in comments question becomes how can worker place data retrieved queue a queue b.

you can try this.

wherever calling task,you can assign task queue.

add.apply_async(queue="queuename1")  notification.apply_async(queue="queuename2") 

by way can put tasks in seperate queue.

worker seperate queues

celery -a proj -q queuename1 -l info  celery -a proj -q queuename2 -l info 

but must know default queue celery.so if tasks without specifying queue name goto celery queue.so consumer celery needed if like.

celery -a proj -q queuename1,celery -l info 

for expected answer

if want pass result of 1 task another.then

result = add.apply_async(queue="queuename1") result = result.get() #this contain return value of task 

then

notification.apply_async(args=[result], queue="queuename2")
