    Interface FunctionProps

    Lambda function configuration for data processing with S3 event and EventBridge integration.

    Defines Lambda function properties for data processing workflows triggered by S3 object events and EventBridge rules in data lake operations.

    Use cases: S3 event-driven data processing; Data transformation; EventBridge-triggered operations

    AWS: Lambda function configuration with S3 EventBridge notifications and custom event rules

    Validation: srcDir must exist; runtime must be valid Lambda runtime; handler must match code structure
