paul-rogers opened a new pull request, #13912: URL: https://github.com/apache/druid/pull/13912
Breaks out catalog-specific changes from the [Catalog Calcite integration PR](https://github.com/apache/druid/pull/13686) to allow easier reviewing. * Changes catalog table entries to Druid types * Enhanced support for external tables, including functions * Revised catalog sync API The key change here is to use Druid types, rather than SQL types, when declaring the schema of a table in the catalog. Druid types better match the actual Druid implementation whereas SQL types are just a SQL "view" on top of the actual Druid types. This change will allow us to use complex types which will be useful for specifying aggregate columns. #### Release note No user-visible changes yet. The docs for the catalog will appear in a later PR after the Calcite integration is complete. <hr> This PR has: - [X] been self-reviewed. - [ ] added documentation for new or modified features or behaviors. - [X] a release note entry in the PR description. - [X] added Javadocs for most classes and all non-trivial methods.
