Apache Nifi 简明教程

Apache NiFi - Remote Process Group

Apache NiFi 远程进程组或 RPG 允许流程使用站点到站点协议将流程中的 FlowFile 直接到不同的 NiFi 实例。在 1.7.1 版本中，NiFi 不提供平衡关系，因此 RPG 用于在 NiFi 数据流中实现负载均衡。

Apache NiFi Remote Process Group or RPG enables flow to direct the FlowFiles in a flow to different NiFi instances using Site-to-Site protocol. As of version 1.7.1, NiFi does not offer balanced relationships, so RPG is used for load balancing in a NiFi data flow.
