The Go lang SDK's fetch function lacks the capability to provide pagination size.

[711openjohn]

The private paging struct reveals

type paging struct {
    Size int     `json:"size"`
    Last *string `json:"last"`
}

and the response of Fetch function

lastKey := ""
if res.Paging.Last != nil {
    lastKey = *res.Paging.Last
}
return lastKey, nil

Where can I find the Size from the response?
