分布式的內存平臺Apache Ignite v1.6.0 發布

Apache Ignite內存數據組織是高性能的、集成化的以及分布式的內存平臺，他可以實時地在大數據集中執行事務和計算，和傳統的基于磁盤或者閃存的技術相比，性能有數量級的提升。 

特性一覽

可以將Ignite視為一個獨立的、易于集成的內存組件的集合，目的是改進應用程序的性能和可擴展性，部分組件包括：

• 高級的集群化
• 數據網格（JCache）
• 流計算和CEP
• 計算網格
• 服務網格
• Ignite文件系統
• 分布式數據結構
• 分布式消息
• 分布式事件模型
• Hadoop加速
• Spark共享RDD
