paul-rogers opened a new pull request, #13627: URL: https://github.com/apache/druid/pull/13627
### Description Another step toward the Druid catalog, this one providing extended functionality to the table functions introduced in an earlier PR. * Revises properties, definitions in the catalog * Adds a "table function" abstraction to model such functions * Specific functions for HTTP, inline, local and S3. * Extended SQL types in the catalog. Primarily for later use, also used to handle types for external tables. * Restructure external table definitions to use table functions * EXTEND syntax for Druid's extern table function * Support for array-valued table function parameters * Support for array-valued SQL query parameters Prior to this PR, MSQ did not support query parameters. This PR starts to provide support. Some of the required functionality will follow in the planner-focused catalog PR. #### Release note See the `reference.md` documentation page in this PR for the revised functionality. Of note are the new table functions and the array table function parameters. This functionality allows the user to, say, reuse the same SQL for every ingest, only passing in a different set of input files as query parameters on each ingest. <hr> This PR has: - [X] been self-reviewed. - [X] 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.
