   We are using PASOE web handlers with annotations in the BE (shown below) to allow access to our data from an ecommerce site. 
   
   @RestAddress (type="collection", address="/LoyaltyHistory/~{CustomerNum}", tables="eLoyaltyHistory", id="CustomerNum",
                 fields="eLoyaltyHistory.*", canRead="true", canUpdate="false", canDelete="false", canCreate="false"
                 ).
   
   If the web developer does not implement batching (limit=100 with the offset) it is possible that they can cause some performance problems. Is there any way to determine if the limit parameter was sent and change if necessary, before the PDS is filled?

   If the limit query parameter is not sent, a default value of 20 records is used (set by the RestEntitiesWebHandler).
   
   The FetchDataRequest object that's passed in to FetchData has that value (whether specified or default) in the NumRecords property, so you can see what that is. That value can also be updated if needed, in individual BusinessEntities. I do not think there's a general event/hook where you can inspect the FetchDataRequest before it's used to retrieve data.

   You're using the RESTful access to the Business Entities using the RestEntitiesWebHandler and the /web/Entities/ endpoint? 
   
   The hardcodedly falls back to NumRecords = 20 when the limit is not provided:
   
   

           IF poWebRequest:URI:HasQueryName("limit":U) THEN
               ASSIGN oRequest:NumRecords = DataTypeHelper:ToInteger(poWebRequest:URI:GetQueryValue("limit":U)).
           ELSE
               ASSIGN oRequest:NumRecords = 20 .

   Yes.

   That will help. 
   
   @Peter and @Mike thanks for the info.
