v1.fieldKeys() function

v1.fieldKeys() function

v1.fieldKeys() was deprecated in Flux v0.88.0 in favor of schema.fieldKeys().

The v1.fieldKeys() function returns field keys in a bucket. The return value is always a single table with a single column, _value.

import "influxdata/influxdb/v1"
v1.fieldKeys(
  bucket: "example-bucket",
  predicate: (r) => true,
  start: -30d
)

Parameters

bucket

The bucket to list field keys from.

*Data type: String*

predicate

The predicate function that filters field keys. Defaults to (r) => true.

*Data type: Function*

start

The oldest time to include in results. Defaults to -30d.

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

*Data type: Duration*
