------------------------------------------------------------
Hello Karuna,
How many records are fetched from DB? And what is the time it takes to fetch
records from DB and to serialize OData response?
To limit the records you could try paging and delta token features supported in
Olingo JPA processor. This shall reduce the time taken for serializing the
records as OData response.
Thanks
Kind Regards

> We have a very large data base and we are exposing the data using olingo
> restful web service. when I compare, time taken to execute the same query via
> jdbc connection and time taken by olingo, there is a significant difference.
> Time taken by Olingo is very large.
> Time taken to process JPA query + Time taken to build response is the total
> time taken by olingo.
> We try to tune the JPA queries using Query hints, but still build response
> time is also very large.
> I have a question :
> Is there any way we can reduce the time taken to build the response ?
