2024/09/12 - AWS Glue - 6 updated api methods
Changes AWS Glue is introducing two new optimizers for Apache Iceberg tables: snapshot retention and orphan file deletion. Customers can enable these optimizers and customize their configurations to perform daily maintenance tasks on their Iceberg tables based on their specific requirements.
