> Currently one can control if sub-query expansion happens via 
> SqlToRelConverter.Config.isExpand(). This flag is global to the query and 
> causes expansion of all supported expression types. For some systems it is 
> required that one can dynamically narrow the set of expressions that should 
> be expanded.
> In order to allow this, I would propose a new setter with a default 
> implementation that returns the above flag.
> {code}
> // a BiPredicate in order to pass both the original query and the expression 
> in question for expansion
> java.util.function.BiPredicate 
> SqlToRelConverter.Config.getExpandPredicate()
> {code}
> If this is OK, I would provide a PR with the relevant changes.
