KeyDB is a multithreading, drop-in alternative to Redis. The Keydb-operator can easily create either a standalone instance (1 replica) or a multimaster setup (3 replicas) of the KeyDB in-memory database. When KeyDB is in multimaster mode, it is possible to have more than one master, allowing for read/write operations across all of them. This capability enhances high availability and fault tolerance.

This operator is part of the Kubernetes operators and tools developed by Krestomatio, a managed service for Moodle™ instances
