Question

I am having degraded performance on the Azure OpenAI - Vector Stores while uploading files

Jos Eilers | Twyzer 5

I am having degraded performance on the Azure OpenAI - Vector Stores while uploading files. The upload of the files is quick, but after that the status is 'In progress'. We are noticing this in the region 'Sweden' on multiple tenants, this also happened before. Is there any solution for this, or is there are information about what is going on?

Hi there Jos Eilers | Twyzer

This could be due to indexing delays, regional service congestion. Since multiple tenants in the Sweden region are experiencing this issue, it might be a regional service issue, check the Azure Service Health Dashboard to see if there are ongoing incidents affecting Azure OpenAI services in that region, try uploading smaller files to see if the delay is related to file size. If the issue continues, consider testing in another region to compare performance. If nothing works do create a support req

If this helps kindly accept the answr thanks much.

Hi Jos Eilers | Twyzer

I just checked in Sweden central for replicating this issue.

As part of my repro, I uploaded 20 small files (under 100 Kb), It was working.

Suggested steps

Agree to Azar on using smaller batches and smaller file size.
Also, would suggest increasing TPM from model deployment for faster indexing.
Switch to another available region.
Change to latest GA API version for existing deployments.

Below are Constraints on file size and type.

The maximum file size is 200 MB. Each file should contain no more than 5,000,000 tokens per file (computed automatically when you attach a file).
Supported extensions- c, .cs, .cpp, .doc, .docx, .html, .java, .json, .md, .pdf, .php, .pptx, .py, .rb, .tex, .txt, .css, .js, .sh, .ts( UTF-8 BOM type)

File search assistant

Network block at customer side

Please check from lag from proxy/firewall side. You can take a network trace using developer tools to find 403's or 401's for needed whitelisting of Azure host urls.

Virtual network doc for Azure OpenAI

Could you let us know if the issue still persists with smaller batch upload (with a screenshot please)

Thank you.
