How do I use Redis / Valkey?

First, you have to go to hosting-panel.net -> Tools -> Valkey Manager and activate it.

When you've activated it, you can use the configuration details listed to configure your given Redis/Valkey compatible system.

Note: If you're not defining a TTL on your Redis keys, we suggest using allkeys-lru as the eviction policy.
