A data engineer creates an AWS Glue Data Catalog table by using an AWS Glue crawler that is named Orders. The data engineer wants to add the following new partitions: s3://transactions/orders/order_date=2023-01-01 s3://transactions/orders/order_date=2023-01-02 The data engineer must edit the metadata to include the new partitions in the table without scanning all the folders and files in the location of the table.
