Hi Nithin,
When analyzing documents using Amazon Textract, pricing can differ significantly based on whether you process documents asynchronously (using StartDocumentTextDetection) or synchronously (using DetectDocumentText). Here's a breakdown of the differences:
- Asynchronous Processing: Pricing: For asynchronous operations, Amazon Textract charges per page. As of now, the price is $0.0015 per page for text extraction. Process: You can send a single PDF or multi-page TIFF file containing up to 3,000 pages in one asynchronous request. This method is cost-effective for larger documents because you are charged per page regardless of the number of requests.
- Synchronous Processing: Pricing: For synchronous operations, Amazon Textract charges per document. The cost is $0.01 per page for text extraction. Process: Each page is processed individually in a separate request. If you have 30 pages, each page would be considered a separate document, resulting in a higher cost compared to the asynchronous method. Cost Comparison: Asynchronous (30 pages in one request):
Cost: 30 pages * $0.0015/page = $0.045 Synchronous (30 separate requests for each page):
Cost: 30 pages * $0.01/page = $0.30 As you can see, asynchronous processing is significantly cheaper for a larger number of pages.
