Pagination based on continuation token

[rkganji]

We have a requirement for clients to get results in paginated way. Pagination was implemented as below:

final CosmosQueryRequestOptions options = new CosmosQueryRequestOptions();
options.setResponseContinuationTokenLimitInKb(2);
options.setQueryMetricsEnabled(true);
        
// Retrieve the documents response using DocumentClient.
Iterable<FeedResponse<Reservation>> feedResponseIterator = container
                .queryItems(query, options, Reservation.class)
                .iterableByPage(continuationToken, 50);
List<Object> docsList = new ArrayList<>();
ResponseWithHeaders result = new ResponseWithHeaders();
FeedResponse<Reservation> page = feedResponseIterator.iterator().next();
String nextToken = page.getContinuationToken();
docsList.addAll(page.getResults());

Issue:
This is working fine when overall result set is less e.g., 120 documents returned as 3 pages. This is not working fine when overall results set is large. When total no. of documents is ~1000, same continuationToken is being returned causing an endless loop and not able to get documents beyond initial 50 docs returned.
