clintropolis opened a new pull request, #19711: URL: https://github.com/apache/druid/pull/19711
### Description changes: * adds `DatasourceBaseTableMetadata`, a catalog model type describing the physical layout of a datasource 'base table'. This metadata is blended with the column declarations to produce a `BaseTableProjectionSpec` to pass to segment generation phase for MSQ insert and replace queries * adds `baseTable` property to `DatasourceDefn` (and friends) to wire up base table metadata in catalog stuff * adds `ClusteredValueGroupsBaseTableMetadata` implementation of `DatasourceBaseTableMetadata` which allows specifying that a datasource should produce clustered segments, containing the clustering column names and optional virtual column definitions. clustered catalog column definitions must match the order of column names in the clustering columns * tables with a base table spec must currently be sealed since the columns list defines the physical spec; validation handles this for virtual column inputs -- This is an automated message from the Apache Git Service.
