StartDominantLanguageDetectionJob

Source: src/AWS/Comprehend/StartDominantLanguageDetectionJob.ts

Runtime binding for comprehend:StartDominantLanguageDetectionJob — start an asynchronous dominant-language detection job over a collection of documents in S3.

The binding is constructed with the data-access role (the IAM role Amazon Comprehend assumes to read the input documents and write results; its trust policy must allow comprehend.amazonaws.com). The role’s ARN is injected as DataAccessRoleArn on every runtime request and the host is granted iam:PassRole on it alongside the comprehend:StartDominantLanguageDetectionJob action (which has no resource-level IAM). Track the job with DescribeDominantLanguageDetectionJob and stop it with StopDominantLanguageDetectionJob.
