Christoph John commented on TEIID-5545:
---------------------------------------

Hello Ramesh,
I would like to come back on you regarding the Olingo topic. I have seen that Olingo 2.0.11 was released in February, and I hope that the next Teiid release 12.0.2 will include it. Is this planned?

Irrespective of this, I am having trouble in working on larger database tables with Teiid
https://issues.jboss.org/browse/TEIID-5643

As I have not found a solution to the topic yet and as this is blocking my further development efforts, I am now trying to go to the latest Teiid version 12.0.1 in the hope that this solves my issue. To do this I again need to replace the Olingo library for my approach to work. I was therefore wondering, if there have been changes in the teiid-olingo-patches-X.jar file between version 11.2.0 and 12.1 that would make it infeasible to just copy the olingo library files over to the files included in teiid 12.1. 
Thanks a lot for your help!

Best regards,
 Christoph

> When using Teiid together with SAPUI5/OpenUI5 Odata V4 model, batch processing does not work as Teiid rejects the "Accept: multipart/mixed" header. The issue has been described in
> https://developer.jboss.org/message/986421#986421
> It has been stated that Olingo in general does support multipart messages and it was recommended to remove the header from the request.
> https://developer.jboss.org/message/986425#986425
>  Unfortunately this seems to be not easily possible when using the SAPUI5 framework. I addressed the issue in the SAPUI5 forum under the following issue:
> https://github.com/SAP/openui5/issues/2288
> The result of this discussion was, that the header is valid for the send content. As I am no expert in the topic I do not really have an opinion on that. However, 
> https://www.w3.org/Protocols/rfc1341/7_2_Multipart.html
> suggests that the header is required. So I am not sure if it is correct or an error to reject the message. However, if Olingo can process the content, it would be great to have a fix for the accept header, or alternatively a config option to enable handling of the Accept header in a way that Olingo processes these data.
