record.get() function

record.get() is experimental and subject to change at any time.

record.get() returns a value from a record by key name or a default value if the key doesn’t exist in the record.

This is an interim solution for the exists operator’s limited use with records outside of a stream of tables. For more information, see influxdata/flux#4073.

Function type signature
(default: A, key: string, r: B) => A where B: Record
For more information, see Function type signatures.

Parameters

r

(Required) Record to retrieve the value from.

key

(Required) Property key to retrieve.

default

(Required) Default value to return if the specified key does not exist in the record.

Examples

Dynamically return a value from a record

import "experimental/record"

key = "foo"
exampleRecord = {foo: 1.0, bar: "hello"}

record.get(r: exampleRecord, key: key, default: "")// Returns 1.0

The future of Flux

Flux is going into maintenance mode. You can continue using it as you currently are without any changes to your code.

Flux is going into maintenance mode and will not be supported in InfluxDB 3.0. This was a decision based on the broad demand for SQL and the continued growth and adoption of InfluxQL. We are continuing to support Flux for users in 1.x and 2.x so you can continue using it with no changes to your code. If you are interested in transitioning to InfluxDB 3.0 and want to future-proof your code, we suggest using InfluxQL.
