Auto-Scaling #18

Closed khteh closed 5 years ago

khteh commented 5 years ago

How does redis cluster handle auto-scaling in/out depends on load?

In the case of Kubernetes cluster, there is horizontal pod autoscaler. Does it work with redis cluster?

Unfortunately, autoscaling is not supported in this setup. You can add a HPA and it will create extra pods, but since the resharding process is manual, it won't have any effect as the new instances won't receive any keys.

As I stated in the README, I advise you to look for alternatives, since the setup in this repository is probably not that future-proof.
