Main

The Main StepFuction is triggered by the DynamoDB Job table stream when a new job is created. This StepFunction orchestrates the task specific StepFunctions.

The Translate job is created by the Main StepFunction. Whilst it is processing the Main StepFunction is paused and waits for a callback. This callback token is stored within the DB.

When Translate completes the translation it will push the translated document into the S3 bucket. An S3 event notification triggers a Lambda function to parse the notification and start the Callback StepFunction. The responsibility of the Lambda function is to determine the job id that relates to this output document.
