Increase Document Intelligence TPS Limit

Question

Increase Document Intelligence TPS Limit

Josh Gottesman 25

We're developing a solution that relies heavily on Azure Document Intelligence for high-volume data extraction from large, scanned PDF documents. The default 15 TPS limit is causing significant sequential processing delays (e.g., processing a ~66-page document takes ~105s). This bottleneck directly impacts our operational efficiency and scalability. We are seeking guidance on the process and requirements for requesting an expedited TPS quota increase to meet our project's throughput demands.

Hey Guys, sorry for the late response! By enabling auto scale and setting up the instances to run in parallel I was able to significantly speed the process up, thank you for all the help!

Answer 1

Default TPS limit: 15 TPS per Azure region per Document Intelligence resource.
Implication: Even if your PDF is large, each page is a separate transaction; so, 66 pages = 66 transactions = ~4.4 seconds minimum, but with concurrency and latency overhead, it goes beyond 100 seconds if processed sequentially.

Requesting a TPS Quota Increase

Step-by-step Process:

a. Go to Azure Portal

Navigate to: Azure Portal - Quotas.

b. Select the Subscription and Region

Choose the Azure subscription and region where Document Intelligence is deployed.

c. Choose the Right Quota Category

Under "Quota type", select Cognitive Services (or AI services, depending on portal view).

Then choose "Document Intelligence (formerly Form Recognizer)".

d. Request Quota Increase

Look for "TPS" quota.
Click Request Increase.
Enter the desired value (60 -100 TPS, depending on your scaling requirement).
In the justification, describe:
- Document size (66 pages)
- Volume (ex: N documents per day/hour)
- Impact (ex: current processing time, business delays)
- Architecture (mention batching/concurrency model)

Alternative Options to Optimize Throughput

Even with quota increases, consider:

Parallel document partitioning: If possible, split large PDFs into smaller segments and process in parallel.
Batch reading with Analyze API: Use the async versions of the Document Intelligence APIs to reduce client wait times.
Regional load balancing: If you have multi-region architecture, split workload across regions (East US, West Europe).
