The Lettuce team is pleased to announce the first beta release of Lettuce 7.4.0!

This release introduces Automatic Client-Side Endpoint Failover through the newly added MultiDBClient.

• Automatic Detection: The client monitors the health of all configured Redis endpoints.
• Seamless Failover: If the active endpoint fails, traffic is automatically rerouted to the next healthiest endpoint based on configurable priorities.
• Customizable: Developers can configure endpoints, set priorities, adjust failure sensitivity, and plug in custom health checks or failure detection logic.

Lettuce 7.4.0.BETA1 supports Redis 2.6+ up to Redis 8.x and requires Java 8 or newer. The driver is tested against Redis 8.4, 8.2, 7.4, and 7.2.

We encourage you to try out this beta and provide feedback ahead of the general availability release.
