outputFilter
A JSONPath expression used to select a portion of the joined dataset to save in the output file for a batch transform job. If you want SageMaker to store the entire input dataset in the output file, leave the default value, $
. If you specify indexes that aren't within the dimension size of the joined dataset, you get an error.
Examples: "$"
, "$[0,5:]"
, "$['id','SageMakerOutput']"
