REDIS is single threaded. So what does it mean when I deploy it to machines with 2 or more cores? How does the single thread utilize these multiple cores?
In: Engineering
It doesn’t. That’s the point – each thread only runs on a single CPU core. If REDIS doesn’t support multiple threads or multiple processes, it will only use 1 core.
Other things can use the other core though. The OS itself, scheduled jobs, remote access, logging, whatever else can use the other core without impacting REDIS.
