DruidUserDefinedTableMacro	Base class for input-source-specific table functions with arguments derived from a catalog external table definition.
DruidUserDefinedTableMacroConversion	Operator conversion for user-defined table macros (functions) based on the TableFunction abstraction defined by the catalog.
ExtendOperator	Druid-specific implementation of the EXTEND operator in Calcite, which is said to have been added for Apache Phoenix, and which we repurpose to supply a schema for an ingest input table.
