Apache NiFi 0.2.0 发布了，该项目目前还处于 Apache 基金会的孵化阶段。 Apache NiFi 是一个易于使用、功能强大而且可靠的数据处理和分发系统。Apache NiFi 是为数据流设计。它支持高度可配置的指示图的数据路由、转换和系统中介逻辑。 架构： 集群管理器： 主界面： 关键特性包括: 基于web的用户界面 无缝体验设计、控制和监视 高度可配置的 数据丢失容错和保证交付 低延迟和高吞吐量 动态优先级 流可以在运行时修改 背压 Back presure 数据来源 从始至终跟踪数据流 为扩展设计 构建自己数据处理器 支持快速开发和有效的测试 安全 SSL,SSH,HTTPS加密内容,等等…… 可插拔的基于角色的验证/授权 主要改进内容包括： Sub-task [NIFI-626] - ExecuteSQL processor for executing arbitrary SQL queries Bug [NIFI-16] - Site-to-site should use canonical hostnames when sending peer list [NIFI-37] - If provenance receive/create/fork/join/clone event registered against flowfile not created in session...
