Actually, I am doing stream processing(stream analytics) using node-red.

**This below link will give more info regarding what I am doing:**

> Hi, I am doing stream analytics using node-red with MQTT and data is coming form OPC. On flow start: Using inject function will minimum time I will initialize common functions, objects, variables, configurations needed for processing the data coming form OPC through MQTT node. First layer: I have couple of flows with 400-500 MQTT nodes. Second layer: Each MQTT output goes to one function node.(Having one for each to add meta data to the message like type of message and index if I am using ar…
