Orchestrate long-running Amazon Bedrock video generation jobs using AWS Lambda durable functions with waitForCondition polling and zero-cost waits
This pattern deploys an AWS Lambda durable function that orchestrates Amazon Bedrock Async Invoke to generate AI videos using Amazon Nova Reel.
The durable function starts a video generation job with StartAsyncInvoke, then polls for completion using waitForCondition with exponential backoff. During each polling interval the function suspends entirely, incurring zero compute charges while Bedrock processes the video.
An S3 bucket is provisioned for video output. The durable execution SDK checkpoints progress at each step, so the workflow is fault-tolerant and idempotent without requiring external orchestration.
