why that is moved out from OperatorPropertiesUtil?
Only called here?

the datasource
I'm not sure if I understand well how this method is used.

But from the name, as far as I understand, retainInputs is not entirely that 
the variables will be used later, but also because of the left-outer join 
semantics?  It means "no matter there is a match or not in the index, output 
the input".

If it's an index left outer join, you have to anyway retain the input so that 
the semantics is correct.

Line 80:     ILogicalExpression[] getConstantExpressions();
Why non-pure requires the addition of getConstantExpressions()?
