clintropolis opened a new pull request, #20377: URL: https://github.com/apache/druid/pull/20377
### Description Follow-up to #19830, this adds a plain table `BaseTableProjectionSpec`, the API side companion of the internal v10 segment metadata `TableProjectionSchema` that we store internally for non-rollup tables. This is mainly going to be useful for catalog and compaction uses since it will allow catalog compaction to always be able to compute a baseTable spec (in a follow-up PR), but it also works anywhere a baseTable is accepted (such as DDL statement base table projection definitions, various ingest specs, etc). This PR also relaxes a restriction on the DDL projection statements to allow any type of `VirtualColumn` to be defined (instead of just `ExpressionVirtualColumn`) by adding a new `supportsOutputNameRewrite`/`withOutputName` functions to let the projection spec match declared names. -- This is an automated message from the Apache Git Service.
