6.1.0.RELEASE

The Lettuce team is delighted to announce general availability of Lettuce 6.1.

This is a massive release thanks to all the community contributions. Most notable changes that ship with this release are:

• Support for Redis 6.2 commands and modifier/argument updates
• Micrometer integration
• CommandListeners API to intercept Redis commands
• extended Keep-Alive options
• Coroutine variant of ScanStream
• TCP NoDelay enabled by default
• Experimental support for io_uring
• Java Flight Recorder Integration for Connection and Cluster Events

Lettuce 6 supports Redis 2.6+ up to Redis 6.x. In terms of Java runtime, Lettuce requires at least Java 8 and works with Java 16.

Thanks to all contributors who made Lettuce 6.1.0 possible.

Micrometer Integration

Lettuce ships an integration for Micrometer. Commands are tracked by using two Micrometer Times: lettuce.command.firstresponse and lettuce.command.completion. The following tags are attached to each timer:

• command: Name of the command (GET, SET, …)
• local: Local socket (localhost/127.0.0.1:45243 or ANY when local distinction is disabled, which is the default behavior)
• remote: Remote socket (localhost/127.0.0.1:6379)

To enable Micrometer, create MicrometerCommandLatencyRecorder from MeterRegistry and register it in ClientResources:

MeterRegistry meterRegistry = …;
MicrometerOptions options = MicrometerOptions.create();
ClientResources resources = ClientResources.builder().commandLatencyRecorder(new MicrometerCommandLatencyRecorder(meterRegistry, options)).build();
RedisClient client = RedisClient.create(resources);

Make sure to have Micrometer on your class path (example from a Maven pom.xml):

<dependency>
    <groupId>io.micrometer</groupId>
    <artifactId>micrometer-core</artifactId>
</tr></table>
