Calcite has a TableFunctionScan, which is a RelNode, takes a function, 0 or more RelNode inputs, and 0 or more other arguments.

RelBuilder does not support TableFunctionScan yet.

add In RelBuilder TableFunctionScanFactory which will create LogicalTableFunctionScan like as for LogicalTableScan and factory for others RelNodes [ example ]
also adding a functionScan method, analogous to the scan method but for table functions.
