> Apache Ignite currently uses Calcite 1.42, which does not support scalar 
> subqueries passed as table function arguments.
> For example:
> {code:java}
> SELECT * FROM TABLE(my_table_function((SELECT value FROM source), 20)); {code}
> The corresponding support was added to Calcite 1.43 under CALCITE-7688. 
> Backport this functionality to the Ignite Calcite module using an isolated 
> planner rule so that it can be easily removed after upgrading to Calcite 1.43.
