             Summary: Processing the certain function predicates after a simple predicates
                 Key: ASTERIXDB-1779
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-1779
             Project: Apache AsterixDB
          Issue Type: Improvement
            Reporter: Taewoo Kim


For example, if we have the following AQL query,

{code}
for $i in dataset MyData
   where $i.id < 5 and edit-distance($i.name, "Arnold") < 2
   return $i;
{code}

It may be better to process *$i.id < 5* predicate first and then process *edit-distance($i.name, "Arnold")* predicate since the processing cost of the latter is higher than the former.
