> It seems that the customization of SqlValidator / SqlToRelConverter /
> CatalogReader in downstream projects is normal.
> E.g. Following are some examples (not all) of extended SqlValidator /
> SqlToRelConverter / CatalogReader from other projects that are using Calcite
> as query planner :
> # DrillValidator

> The class tools/Planner.java[1] is a good customization tool for Calcite
> user. However currently there are no way to use Frameworks.getPlanner()
> directly if the classes need to be customized[2][3].
