- metadata
The metadata for extraction including JSON path, failOnError, and timeZoneId
- expectedDataType
The expected data type for the extracted value

- val columnName: Array[String]
Returns the path to the variant column.
Returns the path to the variant column. For top-level variant columns, this is a single element array containing the column name. For nested variant columns within structs, this is an array representing the path (e.g., ["structCol", "innerStruct", "variantCol"]).

- val expectedDataType: DataType
Returns the expected data type for the extracted value.
Returns the expected data type for the extracted value. This is the target type specified in variant_get (e.g., IntegerType, StringType).

- val metadata: Metadata
Returns the metadata associated with this variant extraction.
Returns the metadata associated with this variant extraction. This may include additional information needed by the data source: - "path": the extraction path from variant_get or try_variant_get. This follows JSON path syntax (e.g., "$.a", "$.b.c", "$[0]"). - "failOnError": whether the extraction to expected data type should throw an exception or return null if the cast fails. - "timeZoneId": a string identifier of a time zone. It is required by timestamp-related casts.
