AWS launched system-managed materialized views in Apache Iceberg to allow users to precompute expensive queries once and reuse results as standard Iceberg tables. These views prevent unauthorized writes by restricting modification rights exclusively to AWS Glue, ensuring the stored results remain consistent regardless of external write permissions to the underlying data.
The materialized views integrate with AWS Glue Data Catalog, enabling any Iceberg-compatible query engine to directly access consistent datasets. Users can define SQL-based materialized views, optionally schedule refreshes, and manage views flexibly while benefiting from governed, always-consistent data sharing. This capability is available in all supported regions for Apache Iceberg.
