Is Celery suitable for this task?

Question

Python

Good day!
There is a python script that takes data from the database and puts it in redis.
This script has 2 methods:
1) updating all data
2) updating the latest data
I want to execute these two methods periodically, 1st time per day, 2nd time in five seconds.
I plan to use Celery, the question is, will Celery tasks execute tasks sequentially? That is, let's say I will use both methods in the same queue, and when the execution of the 1st method starts, the execution of the 2nd will not start until the execution of the 1st is completed? Did I understand everything correctly?
And another question is what is the best practice for such tasks?

Answer 1

Maybe a chain of tasks .
