Hi. I'm sorry because I'm too new in Node Red. I have a lot data coming through my network (MQTT) which is about 10-20 data per seconds (100ms-50ms per data). But here, I just want to get the data into database (influxDB) EXACTLY 1 data per 100ms. No matter how much data I got, I just want to get one data within 100ms cycle. How do I want to do that? I tried interval-length function but I don't really understand it.
As conclusion, I want to display the data in Grafana such like...
2021-03-08 02:00:20.700 ---> 500
2021-03-08 02:00:20.800 ---> 540
2021-03-08 02:00:20.900 ---> 530
2021-03-08 02:00:21.000 ---> 450
2021-03-08 02:00:21.100 ---> 510
All the data have time interval exactly 100ms
