.The `metrics` RHEL system role now supports Valkey as an alternative to Redis This update provides added support for the Valkey in-memory data structure store for the `metrics` RHEL system role. It is an alternative to Redis, which is no longer open source and is being removed from Linux distributions. Valkey is typically used as a high-performance caching layer. It stores data in memory, which accelerates applications by caching frequently accessed data. Additionally, you can use Valkey for other performance-critical operations, for example: * Storing and retrieving user session data. * Real-time communication between different application parts. * Providing fast data access for analytics and monitoring.
