Effective update on UI5 via websocket/OData

[Former Member]

Hi,

First of all I'm a beginner from every aspect in the web development.

However I created a small application (some kind of online monitoring) which displays backend data and refreshed automtically as soon as something relevant is changed on the backend.

Shortly: UI table binded to OData model and I do a model refresh when a message arrives via websocket.

This works, but not the best from performance perspective.

I mean it would be better if only the changed entry would be refreshed or only the relevant entry would be added/deleted on the UI correspondingly to the backend change. 

Is there any recommendation how it should be implemented?

How should be the change communicated via websocket?

How can I refresh only a part of the model/ui table?

Thanks for your help in advance.

Regards,

Gyula

Hi Gyula,

We also have a similar requirement i.e need to send the Notification to a webapplication using websocket, when ever there is data changed in SAP .

I am very new to websocket concept.

Could you guide me how to assign the Odata service to websocket/Push channel .Do we need to have any generic ODATA service as I see a unique service tagged to websocket in S4hana system .

Thanks & Regards
