Summary

AWS Glue adds system‑managed materialized views for Apache Iceberg, storing results as regular Iceberg tables in S3.
Only AWS Glue can write to the view’s data and definition, providing write protection against other users with S3 or catalog access.
Views are defined with SQL, can be scheduled for refresh, and are readable by any Iceberg‑compatible engine via the Glue Data Catalog.
