I am currently implementing redis PUB/SUB in one of my project, and it raises a concern to me, what's the size limitation of a message when PUB/SUB in Redis channel. Was the limit equal to the available memory of the computer? or there will be a threshold in somewhere of config file. Thanks!
Just for your information, I experimented myself, the approximate ceiling size is around 21MB to 22MB on my machine (Debian 5.4.8-1) (it may vary depends on the OS and redis version), it will cause a redis ConnectionError: Connection closed by server.
