Automating Amazon Textract adapter lifecycle management across accounts
AWS ML Blog · rss · 2026-09-28
AWS ML Blog details an automated lifecycle management solution for Amazon Textract Custom Queries adapters, with CloudFormation/Terraform templates:
- Three pain points: cross-account adapter promotion currently requires AWS Support tickets and transfers only trained weights; AnalyzeDocument supports one adapter per page per feature type, requiring upstream routing for multiple form versions; regulated industries need encryption, network isolation, and least-privilege IAM.
- Architecture: S3 ingestion → lightweight pre-classification via DetectDocumentText to identify form version → adapter ID fetched from SSM Parameter Store → Textract extraction → downstream delivery. Production hardening via PrivateLink, CloudTrail, and KMS.
- Promotion strategies: cross-account copy for fewer than 10 adapters; a centralized hub account for many adapters with frequent updates.
- Effect: externalizing adapter IDs to Parameter Store enables zero-downtime production updates in seconds instead of hours or days of coordination.
