why not scan or query return an array ?

[happy-little-one]

I hope it can return a Promise,iterator is a trouble to me, now I have to code like this:

const dbScan = async () => {
  const arr = []
  for await (const item of mapper.scan(Category, { limit: 2 })) {
    arr.push(item)
  }
  return arr
}

I can not image a business scenario that need to be an Iterator.
