Taewoo Kim commented on ASTERIXDB-1779:
---------------------------------------
I just had an another short conversation with [[email protected]]. Chen's idea
is that the system should have flexibility to optimize the order of applying
each predicate. For the guideline, it might be better to associate numeric
cost, rather than putting labels (text, spatial, and etc).

> 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 that of the former.
