DataRequest class

DataRequest encapsulates the filter for the data, a limit on the maximum results returned, a last string associated with the last returned document, and the sorting order by time. last is returned in the responses TabularDataByFilterResponse and BinaryDataByFilterResponse from the API calls TabularDataByFilter and BinaryDataByFilter, respectively. We can then use the last string from the previous API calls in the subsequent request to get the next set of ordered documents.
