How do rate limits work?CodeRabbit enforces hourly rate limits for each developer per organization. WalkthroughThis update enhances a project by integrating AWS Serverless Application Model (SAM) for deploying Lambda functions, improving documentation, and introducing a Lambda batch processing feature with EventBridge scheduling. It streamlines deployment processes, enriches the project's README with detailed templates, and provides a clear guide for using Lambda batch processing, thereby improving automation and consistency in scheduled tasks.
