Varada Catalog

Varada can work with data stored in an Apache Hive data warehouse, as well as with data stored in Apache Iceberg table format. Queries hitting tables under the Varada catalog will get accelerated automatically.

  • Hive: Varada creates a full copy of the Hive catalog, so that you can access all Hive catalog schemes and tables in Varada under the same full path. For example, you can find the Hive table hive.<schema>.<table> in Varada under varada.<schema>.<table>.

  • Iceberg: Varada creates a full copy of the Iceberg catalog, so that you can access all Iceberg catalog schemes and tables in Varada under the same full path. For example, you can find the Iceberg table iceberg.<schema>.<table> in Varada under varada_iceberg.<schema>.<table>.

📘

The Iceberg catalog only works with the Hive metastore, and not with the AWS Glue metastore.

👍

The default catalog names are varada for Hive and varava_iceberg for Iceberg. You can customize these by changing the names of the varada.properties and varada_iceberg.properties files.
