Snowflake has introduced Polaris Catalog, an open-source catalog for Apache Iceberg, aimed at enhancing interoperability and preventing vendor lock-in. Open-source file and table formats like Iceberg are valued for their ability to allow multiple technologies to operate over a single data copy, reducing complexity, costs, and vendor lock-in risks. However, limitations between engines and catalogs have hindered this potential, necessitating difficult trade-offs for data architects and engineers.
Key Features of Polaris Catalog
Interoperability and Flexibility:
- Polaris Catalog builds on Apache Iceberg's open REST API, enabling cross-engine read and write operations.
- Supports integration with multiple engines, including Apache Doris, Apache Flink, Apache Spark, PyIceberg, StarRocks, Trino, and commercial options like Dremio.
- Allows enterprises to use a single data copy across different engines, minimizing storage and compute costs.
Deployment Options:
- Can be hosted on Snowflake's AI Data Cloud infrastructure or self-hosted using containers like Docker or Kubernetes.
- Offers flexibility to switch underlying infrastructure without lock-in.
Governance and Integration:
- Integrates with Snowflake Horizon, extending governance features like column masking policies, row access policies, object tagging, and sharing to Iceberg tables created by various engines.
Future Prospects
Polaris Catalog aims to provide fully interoperable storage for the broader data ecosystem by leveraging Apache Iceberg standards. Snowflake plans to continue enhancing Polaris Catalog, drawing on its experience with global, cross-cloud platforms and the growing Iceberg community.
Availability
- Polaris Catalog will be open-sourced within 90 days and available for public preview on Snowflake infrastructure soon.
Future Plans
Snowflake plans to make Polaris available to its first enterprise customers under preview later in June. The company is also focusing on building up the security features and aligning them with the community standards.
In summary, Snowflake's Polaris Catalog is a significant step towards creating a more open and interoperable data ecosystem, addressing key concerns around vendor lock-in and providing enterprises with greater flexibility and choice.
