Week 5 Worklog

Work Completed

• Studied Lambda event handling and basic Python SDK usage with boto3.
• Designed backend functions for creating upload URLs, starting analysis jobs, and retrieving results.
• Studied DynamoDB partition keys and item design for job status tracking.

Results Achieved

• Chose jobId as the DynamoDB partition key.
• Defined job states: UPLOADED, TRANSCRIBING, ANALYZING, COMPLETED, and FAILED.
• Created a simple API design for /upload-url, /jobs, and /jobs/{jobId}.

Learning Outcomes

• DynamoDB is effective when access patterns are simple and known.
• API design should expose clear states so users can understand asynchronous processing.
