The point of this ticket isn't to cache filtered data, it's to avoid computing the expression twice. It's very common to have a query of the form `select <expression> from t where <expression>`. The point is that `expression` gets computed twice (once for filtering and once for the projection) and we would like to avoid that. -- This is an automated message from the Apache Git Service.
