Dominik Moritz commented on ARROW-2705:
---------------------------------------
I'm trying to build a predicate for multiple columns and it feels a bit clunky.
let pred: predicate.Predicate | null = null;
for (const [col, extent] of extents) {
const newPred = predicate
.col(col)
.ge(extent[0])
.and(predicate.col(col).le(extent[1]));
if (pred) {
pred = pred.and(newPred);
} else {
pred = newPred;
}
}
> CombinationPredicates should take list of predicates

> CombinationPredicate like And and Or only take two predicates: left and
> right. However, it often makes sense to combine more than two predicates. I
> suggest that `and` and `or` support arbitrarily many arguments.
