---------------------------------------
Hi Eugenio,
The paging feature of OData is not just for browser scenarios where someone has
to click a link. Another typical OData use case is to synchronize data to
mobile devices. In case of a lot of data a single feed request also doesn't
work and the synchronisation has to be implemented page by page. Many OData
service are limited by server side paging. Actually this means Excel as a OData
client should deal with pages at least as a feature. Maybe you have to find out
if Excel already supports this.
Is it the JPA processor which you are using? Then Carl is right and issue 27
needs to be solved first.
Greeting,
Stephan
> Processor interceptor and data stream

> Key: OLINGO-72
> URL: https://issues.apache.org/jira/browse/OLINGO-72
> Project: Olingo
> Issue Type: Improvement
> Components: odata2-core
> Affects Versions: V2 1.1.0
> Reporter: Eugenio Lentini
>
> Good morning,
> I have two questions/improvements for olingo:
> 1) a sort of processor interceptor for authorization: for the time being I
> have implemented a processor in order to perform the authorization of my
> odata service.
> Some clients, such as MS-Excel, want a specific answer in order to send
> user:pass so I have put this response with error 401 inside of a processor
> which is created by the Factory. Once the client has sent the credentials I
> can instantiate, always inside of the factory, the processor to build the
> atom feed.
> 2) stream data to the client: I have a lot of data, may be big data, and I
> cannot load all of them in memory for the conversion so it would be great to
> have a way to have access to the response object, or another way, to stream
> data to the client and not in one shot.
> If it is already possible could you please suggest the method or document it?
> In case I could even send you a working example to save up your time.
> Thanks a lot for the attention and the work you are doing.
> Eugenio
