schema.measurementFieldKeys() function
The schema.measurementFieldKeys() function returns a list of fields in a measurement.
The return value is always a single table with a single column, _value.

schema.measurementFieldKeys(
bucket: "example-bucket",
measurement: "example-measurement",
start: -30d
)
Parameters
bucket

measurement
Measurement to list field keys from.
start
Oldest time to include in results.
Defaults to -30d.
