AWS Glue Crawler now supports the ability for customers to bring their own custom JDBC drivers to extract data schemas from data sources and populate the AWS Glue Data Catalog. Glue Crawlers already support JDBC Glue connections to supported data sources on AWS. Now, you can bring your own JDBC driver versions to connect to data sources in Glue Crawlers. These data sources include Postgres, MySQL, Oracle, SQL Server, and Amazon Redshift.
