AIStor Tables

MinIO announced AIStor Tables as a Technical Preview on September 30th, 2025.

AIStor Tables implements native Iceberg tables support in AIStor object storage. This feature allows users to create, manage, and query Iceberg tables directly through AIStor Object Store with no dependencies on external catalog services or metadata databases.

AIStor Tables implements a subset of the Iceberg REST Catalog spec functions. Applications can interact with Iceberg entities through the AIStor Iceberg API while performing S3 operations through the object storage API.

The following diagram provides a visual flow of how applications like Starburst, Dremio, Trino, and Spark can use either the Iceberg or S3 APIs to access distinct types of data stored in AIStor.
