--------------------------------------------
{quote}Would it be acceptable to replicate (clone) PredicateAnalyzer logic
across all adapters ?{quote}
What do you mean by "all"? Do you include Jdbc adapter as well?
I'm afraid different adapters might have different ways to represent
expressions and the set of supported expressions might vary.
> Evaluation of predicate "(A or B) and C" fails for MongoDB adapter
