v1.tagKeys() function

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

The v1.tagKeys() function returns a list of tag keys for all series that match the predicate. The return value is always a single table with a single column, _value.

import "influxdata/influxdb/v1"

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



Bucket to return tag keys from.

Data type: String


Predicate function that filters tag keys. Defaults to (r) => true.

Data type: Function


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


import "influxdata/influxdb/v1"

v1.tagKeys(bucket: "my-bucket")
