Redis Lettuce 5 5.1.0.M1 最新版

Tags：软件开发开发环境

Lettuce是一个可伸缩线程安全的Redis客户端。多个线程可以共享同一个RedisConnection。它利用优秀netty NIO框架来高效地管理多个连接。

Lettuce特色

Lettuce 5.1.0.M1 发布，这是 Lettuce 5.1 发布的第一个预览版本，包含改进和错误修复。Lettuce 5.1.0.M1 需要 Java 8，Java 9 或 Java 10 环境。

此次比较显著的变化有：

Redis Streams 的 API 预览

异步池实现

SCAN 流和初始化

全局命令超时（默认情况下禁用）

主/从和 Sentinel 的异步连接方法
