eric-maynard opened a new pull request, #1466: URL: https://github.com/apache/polaris/pull/1466
Polaris recently added support for catalog federation in #1305, which allows a Polaris instance to federate requests against a given catalog to another Polaris instance. This is useful for deployments with multiple Polaris instances where one primary instance should defer to another for requests against a given catalog: <img width="350" alt="Screenshot 2025-04-25 at 1 39 19 PM" src="https://github.com/user-attachments/assets/9dac7cd7-2108-495b-ac1d-cc5f2b3eaba1"; /> However, many deployments also have _other_ catalogs in use. For example, some legacy data may be stored using the file-based Hadoop catalog, one part of the organization may be using a vendor's Iceberg catalog, and there could be a team that's been using a Hive catalog. In order for Polaris to federate to these various catalogs, we can deploy Polaris in _wrapper mode_ against these catalogs: <img width="350" alt="Screenshot 2025-04-25 at 1 42 59 PM" src="https://github.com/user-attachments/assets/78204d0d-3b5d-4cee-a899-75d8dd90d9f0"; /> This PR introduces the configurations related to this wrapper mode, and implements a simple wrapper for HadoopCatalog. -- This is an automated message from the Apache Git Service.
