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.
