Hi all, I am currently working a bit on my little PLC4X + IoTDB Home automation project which I plan to use to make little videos about IoTDB features. Right now, what I’m trying to figure out, is how can I define a streaming query?
I have multiple devices, each one providing numerous measuements. The ones I’m interested now, is one where all my weather data is stored (Wind, Rain, Humidity, Temperature, …) I have a little frontend, that displays the current values using a “LAST(*) query. Now I would like to have a streaming query, which returns either all last values whenever one of the values changes. Or a stream of changes for only the values that actually changes. I’m a bit stuck at to how to do this using the Java API. Help greatly appreciated. Chris
