# AWS Lambda Java Integration Patterns for creating high-performance AWS Lambda functions in Java with optimized cold starts. ## Overview This skill provides complete patterns for AWS Lambda Java development, covering two main approaches: 1. **Micronaut Framework** - Full-featured framework with AOT compilation, dependency injection, and cold start < 1s 2. **Raw Java** - Minimal overhead approach with cold start < 500ms Both approaches support API Gateway and ALB integration with production-ready configurations. ## When to Use - Deploying Java functions to AWS Lambda - Optimizing cold starts below 1 second - Choosing between Micronaut and Raw Java approaches - Configuring API Gateway or ALB integration - Setting up CI/CD pipelines for Java Lambda ## Instructions ### 1. Choose Your Approach | Approach | Cold Start | Best For | Complexity | |----------|------------|----------|------------| | Micronaut | < 1s | Complex apps, DI needed, enterprise | Medium | | Raw Java | < 500ms | Simple handlers, minimal overhead | Low | **Validate**: Confirm the approach fits your use case before proceeding. ### 2. Project Structure ``` my-lambda-function/ ├── build.gradle (or pom.xml) ├── src/main/java/com/example/Handler.java └── serverless.yml (or template.yaml) ``` **Validate**: Verify project structure matches the template. ### 3. Implementation Examples #### Micronaut Handler ```java @FunctionBean("my-function") public class MyFunction implements Function<APIGatewayProxyR...
