Redisson 3.9.1 和 2.14.1 已釋出，Redisson 是架設在 Redis 基礎上的一個 Java 駐記憶體資料網格(In-Memory Data Grid)。

Redisson 在基於 IO/">NIO 的 Netty 框架上，充分利用了 Redis 鍵值資料庫提供的一系列優勢，在 Java 實用工具包中常用介面的基礎上，為使用者提供了一系列具有分散式特性的常用工具類。使得原本作為協調單機多執行緒併發程式的工具包獲得了協調分散式多機多執行緒併發系統的能力，大大降低了設計和研發大規模分散式系統的難度。同時結合各富特色的分散式服務，更進一步簡化了分散式環境中程式相互之間的協作。
