I’ve read several topics about schema recommendation and also about data homogeneity within one measurement. I am not sure if data schema I used is correct.
In short, the question is: Is recommendation regarding schemas homogeneity from InfluxDB schema design recommendations and best practices | InfluxDB Cloud Serverless Documentation is also valid for InfluxDB v2 OSS?
Problem description: I created a solution without previous experience with InfluxDB v2. I used one measurement, where I save data from devices: temperature sensor and some device. Let’s imagine folloiwing parameters:
field1_key == “temperature”, field2_key == “voltage”, tag_key == device_id.
Question: Does it mean that every point in InfluxDB will contain all keys, but some of them will contain just NULL value?
