experimental.set() function	The `experimental.set()` function sets multiple static column values on all records.	influxdb_cloud_ref name parent experimental.set Experimental	302	/influxdb/cloud/reference/flux/stdlib/built-in/transformations/set/

The experimental.set() function sets multiple static column values on all records. If a column already exists, the function updates the existing value. If a column does not exist, the function adds it with the specified value.

Once sufficiently vetted, experimental.set() will replace the existing set() function.

Function type: Transformation

import "experimental"

experimental.set(
  o: {column1: "value1", column2: "value2"}
)

Parameters

o

A record that defines the columns and values to set. The key of each key-value pair defines the column name. The value of each key-value pair defines the column value.

Data type: Record

Examples

Set values for multiple columns
