When an S3 object lands in the permits/incoming/ prefix, a rule should start a validation workflow without polling the bucket. Which service pattern should developers implement?
Select an answer to reveal the explanation.
Short Explanation
Do not send a librarian to walk the shelves every minute looking for a new folder. When the object lands under permits/incoming/, fire an EventBridge (or S3) event straight into the validation workflow. No polling required.
Full Explanation
Event-driven patterns with Amazon EventBridge (and S3 event notifications) react to object-created events and invoke targets such as Lambda, Step Functions, or SQS without listing the bucket. Cron-based polling adds latency and cost. RDS triggers are unrelated to S3 object arrival, and manual console gates defeat automation. Prefix filters keep the rule scoped to permits/incoming/.
