Interface IngestDotExpanderProcessor

Name	Type	Description
field	Field	The field to expand into an object field. If set to *, all top-level fields will be expanded.
override	boolean	Controls the behavior when there is already an existing nested object that conflicts with the expanded field. When false, the processor will merge conflicts by combining the old and the new values into an array. When true, the value from the expanded field will overwrite the existing value.
path	string	The field that contains the field to expand. Only required if the field to expand is part another object field, because the field option can only understand leaf fields.
