> Execution-related classes have no third-party dependencies except for apache calcite. The only thing connecting them is the RelDataType class, describing a type of the row.
> Seems the only actual usage of row type is inside {{CorrelatedNestedLoopJoinNode}}.
> So let's get rid of unnecessary coupling by reworking {{CorrelatedNestedLoopJoinNode}} class.
