Describe the feature:
In ECS there is a high possibility to have thousands of fields with no value and a very small portion of them to be useful. We would like to distinguish these fields in the UI.
To accomplish so we need this information from ES. This PR introduces a query parameter
drop_null_columns
elastic/elasticsearch#102428 which returns the null columns in a separate property.I have already a PoC ready #174585 to test the new api. It works just fine.
