The Lettuce team is pleased to announce the Lettuce 7.4.0 minor release!

✨ New: MultiDbClient Lettuce introduces MultiDbClient, providing client-side failover and failback across multiple Redis databases.

MultiDbClient is designed to support client-side geographic failover, improving availability by monitoring the health of configured Redis endpoints and automatically switching connections when a database becomes unavailable. See the docs for details and more examples.

Lettuce 7.4.0 supports Redis 2.6+ up to Redis 8.x. In terms of Java runtime, Lettuce requires at least Java 8 and works with Java 24. The driver is tested against Redis 8.6, Redis 8.4, Redis 8.2, Redis 8.0, Redis 7.4 and Redis 7.2.

Thanks to all contributors who made Lettuce 7.4.0.RELEASE possible.

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.

• Upgrading to Netty 4.2

Lettuce 7.0.0.RELEASE supports Redis 2.6+ up to Redis 8.x and requires Java 8 or newer. The driver is tested against Redis 8.2, 8.0, 7.4, and 7.2.
