What is the maximum number of concurrent request using DSS api for vbd file downloads

Hi,

We are using DSS Rest API's for downloading the vbd files. We currently download vbd files and instrument files for 17 venues, so total 34 files using 17 threads. Sometimes we are getting -1 for the http status code, which might be happening due to no valid http response from DSS.

Just wanted to understand what is the limit on the DSS side for vbd and instrument file downloads if we use a single account.

Can anyone point us to what could be the possible issue here .

We are runnnig this on a 16 core ec2 machine.

Thanks

Hello @govardhan.yernagula,

Hi Zoya,

Thanks for the response.

Do we have any working Java code examples for downloading vbd directly from aws as documented in the tick history guide. There seems to be no limit on the direct downloads from aws.

Hello @govardhan.yernagula,

Please check with DSS Best Practices to make sure you are within recommended on VBD retrival.

Please make sure you are not requesting custom extractions on the same account in parallel. 4 is a total on all requests, not VBD only,

If you find the behavior not as expected:

"You can have up to four extraction downloads in progress at one time. This total applies to any
combination of custom reporting and Venue by Day downloads, via any combination of the REST API and
via the GUI.

the best way is to open a support case by going on

Get Support -> Product & Contenty -> Datascope

Include the complete info on your requests issued, your id, times, etc.

Thanks,
