Bertil Chapuis commented on CALCITE-5309:
-----------------------------------------
Thanks a lot for your answer, it helps a lot.
Could you elaborate a little bit more on the method you mention (i.e., 'RelNode
implementCursor(int)')? More precisely:
* I'm not sure to understand the 'int' parameter. I would expect the input of
the cursor to be a sub query (e.g., 'cursor(select * from
table(s.GenerateStrings(?)))'). In my previous attempts at implementing
cursors, I tried to implement the cursor with a method that takes an
Enumerable<Object[]> as a parameter.
* Is there a specific location in the codebase (package or class) where you
expect this method to be located?
> Accept cursors as inputs of table functions

> The TableFunctionTest.testTableFunctionCursorsInputs is currently disabled
