/**
* The {@link SkipIndexPredicate} is a predicate that prevents
* an index from being used on the wrapped predicate.

* It isn't exposed as user API; it will only be created when
* making use of index suppression option in the
* {@link SqlPredicate}
*
* SkipIndexPredicate also isn't send over the wire; so we don't
* need to worry about backward compatibility in future releases.
