Hey all, I was integrating our Java IcebergIO with Beam SQL (PR #34799 <https://github.com/apache/beam/pull/34799>) and got blocked on the fact that Beam SQL currently lacks a "Catalog" concept. This is fundamental to modern data architectures like Iceberg, where they are used to manage table metadata and enable broad ecosystem integration.
To address this gap, I've opened a new PR (#35223 <https://github.com/apache/beam/pull/35223>), which introduces the *Catalog* and *CatalogManager* interfaces, enabling support for: - CREATE CATALOG my_catalog TYPE 'local' PROPERTIES (...) - SET CATALOG my_catalog - DROP CATALOG my_catalog I left a more detailed overview in the PR description. My hope is that this foundational change will benefit not just IcebergIO, but also other IOs and future Beam SQL integrations. Please take a look and share any feedback, especially regarding major architectural concerns. I'm working on a short timeline, so minor enhancements can be noted for follow-up PRs. Thank you! Ahmed
