Athena enhances read support for Delta Lake table format

You can now query Delta Lake tables seamlessly in Amazon Athena, giving you the benefit of increased operational efficiency, improved query performance and reduced cost. Delta Lake is an open-source table format that helps implement modern data lake architectures commonly built on Amazon S3. Prior to this launch, reading Delta Lake tables in Athena required a complex process of generating and managing additional metadata files. Now you can use Athena to query Delta Lake tables directly without this additional effort.
