Performance Note
Although InfluxDB has an extremely impressive ingestion rate (meaning it can record very large numbers of properties quickly), it has a critical flaw when being used for industrial data - it can't show instantaneous values.
This means that if you've got a sample at 10:00 and another at 11:00, asking for data at 10:20-10:40 will give you no results.
Compensating for this issue causes queries to be significantly slower than they should be.
