Describe the feature:
A function a
Lensconsumer can import and given a formula string, return a parsed result as list of columns to use asEmbeddableattributes.Describe a specific use case for the feature:
When a consumer wants to integrate a
Lensinstance within his plugin and wants to provide a Formula operation for a dimension, the current setup requires the consumer to manually craft a formula string AND all the referenced columns with the right parameters in sync.In particular case this can be a long and tricky task, for instance when using filtered metrics or long formulas.
