How can the redis connection pool be kept consistent across multiple uwsgi worker processes?

edit

In order to keep the Redis connection pool consistent across multiple uwsgi worker processes, you can use a shared connection pool object. One way to achieve this is by using a connection pool library such as redis-py and initializing the connection pool object outside of the worker processes.

Here's an example code snippet:

import redis
from uwsgidecorators import postfork

redis_pool = None

@postfork
def init_redis_pool():
    global redis_pool
    redis_pool = redis.ConnectionPool(host='localhost', port=6379)

def my_view(request):
    redis_conn = redis.Redis(connection_pool=redis_pool)
    # Use redis_conn to interact with Redis

In this example, the init_redis_pool function is called after the uwsgi worker processes have been forked. It initializes a global redis_pool object that is shared across all worker processes.

Then, in your views or other code that interacts with Redis, you can create a Redis connection using the shared pool:

redis_conn = redis.Redis(connection_pool=redis_pool)

This ensures that all worker processes are using the same Redis connection pool and avoids issues with inconsistent connections.
