AWS Glue now provides column importance metrics in the FindMatches machine learning transform

The FindMatches ML transform in AWS Glue now includes information on how much each column in the dataset contributed to determining if records were matches. The FindMatches transform enables you to identify duplicate or matching records in your dataset, even when the records do not have a common unique identifier and no fields match exactly. This feature makes it easier to decide how to improve your FindMatches transforms.
