What Is Apache Polaris? Why Open Data Catalogs Matter and How to Use Them with AWS
Apache Polaris is an open-source implementation of the Iceberg REST Catalog specification, designed to provide a unified metadata and governance layer for Apache Iceberg tables across multiple platforms. It supports cross-platform query engines and cloud providers, enabling organizations to avoid vendor lock-in while maintaining consistent access controls and governance. Polaris operates alongside existing catalogs like AWS Glue and Snowflake Horizon, serving as a standardized, interoperable layer in lakehouse architectures.
