schema.fieldKeys() function

Flux 0.88.0+

The schema.fieldKeys() function returns field keys in a bucket. The return value is always a single table with a single column, _value.

import "influxdata/influxdb/schema"

schema.fieldKeys(
  bucket: "example-bucket",
  predicate: (r) => true,
  start: -30d
)

Parameters

bucket

The bucket to list field keys from.

predicate

The predicate function that filters field keys. Default is (r) => true.

start

The oldest time to include in results. Default is -30d.

Relative start times are defined using negative durations. Negative durations are relative to now. Absolute start times are defined using time values.

Examples

import "influxdata/influxdb/schema"

schema.fieldKeys(bucket: "my-bucket")

Function definition

package schema

fieldKeys = (bucket, predicate=(r) => true, start=-30d) =>
  tagValues(bucket: bucket, tag: "_field", predicate: predicate, start: start)

Used functions: schema.tagValues

Supported in the InfluxDB Cloud UI

The schema package can retrieve schema information from the InfluxDB Cloud user interface (UI), but not from the Flux REPL.
