Protected Server

If you are running a Level 1 cluster, one of your server containers will be running the database and Redis servers. In this case, you can add the environment variable NO_PROCESS_FLOWS=true in the docker-compose file or the .env file.

This is only required for high load scenarios and usually when 3 or more servers in your cluster. It will prevent that server from executing flows, leaving resources free for the database and Redis.

If you are running a Level 2 cluster (database and Redis are in external clusters of their own) then you do not need to protect your servers.
