Hi @cmendolsohn

Thanks for the update. Within Refinitiv Workspace (RW), the RD Libraries are retrieving streaming data from the API Proxy which is presently accessing a different backend streaming server than the apps (News App for example). However, I will need a more detailed explanation if this would justify the difference. I've reached out to someone from the Desktop team to better understand the setup and whether the configuration, for example QoS (Quality of Service) could affect the delivery of updates. What I can tell you is that the library does not throttle updates.

Also, there is an initiative happening to update the API Proxy to point to the same backend streaming server being used by the Apps. Assuming this would make all things equal, in theory, this should resolve the delay. I will update once I get clarification/confirmation with my current assumptions.

Hi,

I'm following up on this issue, which I have observed for 2 consecutive weeks now. See the following Youtube video, which captures the data transmission latency issue I've been describing.

There is definitely a visually noticeable latency in the API data transmission, which I've observed on weekends. Notice how in the clips from July 1st, the news items show up noticeably earlier in the Desktop instance. My best guess is that there is some kind of API setting that is restricting the response rate in data transmission.

If it was only limited to weekends, it wouldn't be too big of a deal, but the next logical question is, when else is this throttling mechanism being implemented?

Hi @cmendolsohn ,

The moderators on this forum are expertise on Refinitiv APIs usage. However, they do not have deep expertise in every type of product available through Refinitiv products. Such expertise is available through Refinitiv Helpdesk, which can be reached via MyRefinitiv. To be of help, ticket number 12717614 was raised on your behalf and the support team is going to contact you soon to assist with this.

Hope this helps and please let me know in case you have any further questions

Hi @cmendolsohn ,

Could you please provide the example code that gets "streaming news" for further investigation?

using var stream = Pricing.Definition().Universe("NFCP_UBMS").GetStream()
                                                             .OnUpdate((item, update, s) => DisplayUpdate(item, update))
                                                              .OnError((item, err, s) => Console.WriteLine(err));

The code is pretty straightforward - its right from your Github examples.
