Page Size Considerations
You can use page size for data services and form services (application stack) to indicate the number of records that the AIS Server fetches at a time through the HTML Server. Using this functionality may help when the data or form request expects a large data set. The data request or the form request, instead of requesting all of the records in a single operation, can request a chunk at a time, store (buffer) the record on the AIS Server, and then return the complete set of records in the response to the caller.
For a form service, it is important to consider where to place the "Return Form Data" action when you want the orchestration to return grid data. If your application stack contains multiple forms with grids, and you want to use the paging option to return all the data for a grid, you must place the "Return Form Data" action after the Find action.
