experimental.set() function

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

The experimental.set() function is subject to change at any time. By using this function, you accept the risks of experimental functions.
