Polaris Catalog Is Now Open Source

Posted on by

Just as large communities have grown in support of open source projects for open file and table formats, there is a community emerging to collaborate on standards for metadata catalogs. Diversity of ideas and community contributions creates the most interoperable catalog across the widest variety of tools. 

Polaris Catalog implements Apache Iceberg’s REST catalog specification, which means it already enables interoperability with Apache Doris™, Apache Flink™, Apache Spark™, Daft, DuckDB, Presto, SingleStore, Snowflake, Starburst, Trino, Upsolver and more. In addition, Alation, ALTR, Atlan, Collibra, dbt Labs, data.world, Dremio, Confluent, Fivetran, Google Cloud, Immuta, Microsoft, Project Nessie, and Salesforce also intend to add integrations or make contributions to the Polaris Catalog open source project.
