dynamodb pagination

Question

i try to use pagination. but how can i control if querystring parameters changes or do i have to control? 
there is sentence here: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Query.Pagination.html
that says: "Construct a new Query request, with the same parameters as the previous one" at step 2.
maybe i don't have to control query string parameters but at least page parameter will change for every api call.
if i have to check querystring parameters how?

Answer

> querystring parameters changes or do i have to control

Im not sure on which querystring params you are referring to but pagination works like this:

1. Request up to 1MB of data
2. DynamoDB returns 1MB and provides you with a `LastEvaluatedKey` which is a pointer to the last item it read
3. In subsequent requests, you pass `LastEvaluatedKey` to the `ExclusiveStartKey` parameter, which tells DynamoDB where to begin reading
4. This logic keeps happening until there is no `LastEvaluatedKey` returned, which means you have read all the data available.
