    Description copied from interface: CustomTableResolver
    
    Register the table names as extracted from the FROM clause.
    Calcite doesn't provide these full names to table providers and queries them with individual parts of the identifiers without giving any extra context. So if a table provider needs to implement some custom table name resolution strategy it doesn't have information to do so. E.g. if you want to take the compound SQL identifiers that were originally split by dots, join them into a single string, and then query a back-end service, this interface makes this possible.

    Description copied from interface: TableProvider
    
    Returns a sub-provider, e.g. sub-schema. Temporary, this logic needs to live in BeamCalciteSchema.
