Long response time for Composite Extraction Request

sabine.wall

I am trying to make Composite Extraction Request for 1 instrument and 25 fields, but it takes 10-20s to get a response. Any ideas what could be the issue here?

                var extractionsContext = new ExtractionsContext(new Uri("https://selectapi.datascope.refinitiv.com/RestApi/v1/"), "acc", "pw");

                var extractionRequest = new CompositeExtractionRequest
                {
                    IdentifierList = SubjectIdentifierList.CreateInstrumentIdentifierList(new[]
                        {
                            SubjectIdentifier.CreateInstrumentIdentifier(isin, IdentifierType.Isin, null, null, null,  null)
                        }, null, false),
                    ContentFieldNames = new[] {
                        "Instrument ID",
                        "Instrument Full Name - ESMA",
                        "Asset Type",
                        "Currency Code",
                        "MIC",
                        "Market MIC",
                        "Price Quote Method Code",
                        "Maturity Date",
                        "Coupon Rate",
                        "Accrued Interest",
                        "First Coupon Date",
                        "Coupon Frequency Description",
                        "Previous Coupon Date",
                        "Next Pay Date",
                        "Day Count Code Description",
                        "Mid Price",
                        "Close Price",
                        "Bid Price",
                        "Ask Price",
                        "Mid Dirty Price",
                        "Bid Dirty Price",
                        "Ask Dirty Price",
                        "Mid Clean Price",
                        "Bid Clean Price",
                        "Ask Clean Price",
                    }
                };

                //Extract
                var extraction = extractionsContext.ExtractWithNotes(extractionRequest);
                var extractedRows = extraction.Contents;

I ran the same extraction request in Postman multiple times and found the elapsed times varied from 5 to 15 seconds. However, sometimes, the elapsed time is more than 20 seconds.

From this finding, the problem isn't specific to DSS .NET SDK.

It will be helpful if you can confirm that the long response time issue also happens in Postman. You can download the DSS REST Tutorials Postman collection from the Refinitiv Developer's Website.

Then, we need to contact the server team to confirm if this is expected behavior.
