Can anyone let me know on how to use the HTTP Server Origin stage to fetch large volume of records

My problem statement is, I need to fetch large volume of data from a source using GET call. We can use HTTP Client stage for the same but since the source application doesn't have pagination configured , we will receive all the records at once . Thus i want to use HTTP server stage to achieve the same. Can anyone suggest how to achieve this. 

Appreciate your help!!

Thanks in Advance!!
