DSDataRequest - large volumes of data going OUT of the network

I am using ThomsonReuters.DswsApi DSDataRequest and have run a few times (five or six) for an Index and maybe 60 data columns

So out going data should be small enough. However our network is alerting us of large volumes of data going OUT of the network within a short period of time (1GiB+) to datastreamwide.refinitiv.com

Any idea why this is happening ?

DSDataRequest reqDSRequest = new DSDataRequest()

{

Instrument = new DSInstrument(arrSecurities),

DataTypes = new DSDataTypes(arrColumns),

Date = new DSSnapshotDate(DSDateType.Literal(DSDateLiterals.LatestDate))

};

DSDataResponse resDSResponse;

resDSResponse = DSClient.DataService.GetData(reqDSRequest);

Thanks

Hi @fergal.twomey,

May I ask:

Are you coding this in JAVA?

What is the list of instruments and fields you are requesting exactly?

fergal.twomey

Hi - it's in C#

Running for an index, and then for approx 300 stocks. About 50 columns - GICS classifications (sector, industry, industry groups etc and their codes), market values, prices etc.

The outgoing data I would have thought would be very small

Hi @fergal.twomey, Have you had a look at the DSWS product page on the developers forum? It contains a link to the usage and limits document. Specifically, it looks like the data limit is reached with your call, no?

a) 10 instruments x 10 datatypes

b) 50 instruments x 2 datatypes

c) 2 instruments x 50 datatypes

Sorry I checked, it is 50 (or less) datatypes at a time, and one instrument (it is an Index name)

When running for example 300 sedols, we split up to to two instruments at a time.

Anyway we are getting data back, there is no issue there, there is no Datastream error.

The issue is our network is alerting us of large volumes of data going OUT of our network within a short period of time (1GiB+) to datastreamwide.refinitiv.com.

However it's hard to see how a request of 300 sedols and 50 data column names could be considered a large volume of data. I wonder is the DSDataRequest very big regardless of teh instrument and datatypes been passed

Hi @fergal.twomey, it would appear that your access ID is being shared. The owner of this ID is Eoin Fahy. You are requesting much more than 300 hundred sedols on this ID and under 50 datatypes on a daily basis. We will need to block your usage until this security breach is investigated, Please speak with your account manager to speak about your next steps.

fergal.twomey

This is a production environment - it is not appropriate to block our access!

james.bright0

There is a security breach with this ID. Please speak with your account manager to regain access as soon as possible.

fergal.twomey

What is the security Breach - we are permissioned for10000 stocks. Eoin Fahy's id is used for the process.

I am putting in a technical support question, and your response is to block our production id which is now causing a production issue!!!!
