better pagination support

[mohammad-bolt]

right now for pagination it makes an expensive count query

tota: table(
    order_by: $order_by
    where: $where
  ) {
    aggregate {
      count
      __typename
    }

which is expensive for RDS.

can we customize it so we can turn it off? this way we can use partial pagination
