Different Application sharing same redis instance

[lee-jian-hui]

How can i properly use redbeat to handle different celery instances sharing the same redis instance?

In my case, the redbeat will lock the scheduler associated with app A and then the scheduler with app B is not able to lock. But logically, they are separate celery instances, why will the lock persist through different celery instances?

Do they use separate Redis databases (last argument in connection URL: 0, 1, 2)?
