How do you handle errors and retries when using custom event sources with AWS Lambda?
- Halt execution and alert administrator
- Ignore errors and proceed with execution
- Implement error handling and exponential backoff
- Retry immediately on failure
When using custom event sources with AWS Lambda, it's best practice to implement error handling mechanisms such as exponential backoff to manage retries and handle errors gracefully.
What are the best practices for monitoring and logging custom event sources in AWS Lambda?
- Disable logging to reduce overhead
- Manual logging in function code
- Use third-party logging services
- Utilize CloudWatch Metrics and Logs
Best practices for monitoring and logging custom event sources in AWS Lambda include utilizing CloudWatch Metrics and Logs to track function invocations, errors, and performance metrics.
Custom event sources enable AWS Lambda functions to respond to __________.
- Built-in events
- Custom events
- System events
- Third-party events
Custom event sources enable AWS Lambda functions to respond to custom events, allowing for integration with various services and applications.
When configuring custom event sources, it's essential to define the appropriate __________ for event processing.
- Event mapping
