What can cause Redis timeout?

Redis client uses a single TCP connection and can only read one response at a time. Even when a first operation times out, it does not stop the data being sent to/from the server. Because of this, it blocks other requests and causes timeouts.

What is Redis connection timeout?

The maximum length of time to wait while establishing a connection to a Redis server.
