aws-sdk-java-v2-lambda

Invoke Lambda functions using the AWS SDK for Java 2.x by creating a LambdaClient, constructing an InvokeRequest with your function name and payload, and calling invoke() for synchronous or invokeAsync() for asynchronous execution. Handle responses via InvokeResponse or track asynchronous invocations with futures.

Yes. AWS SDK for Java 2.x enables creating, updating, and managing Lambda function code, environment variables, layers, and aliases through dedicated operations on LambdaClient. Use UpdateFunctionCodeRequest, UpdateFunctionConfigurationRequest, and related methods to modify function properties.

Convert Java objects to JSON using standard serialization libraries, encode payloads as SdkBytes, and pass them in InvokeRequest. Parse response payloads from InvokeResponse as JSON strings or typed objects, enabling bidirectional structured data exchange between Java and Lambda.

Yes. AWS SDK for Java 2.x integrates with Spring Boot to simplify Lambda client setup and dependency injection. Spring Boot patterns streamline LambdaClient and LambdaAsyncClient configuration, enabling cleaner application code for Lambda operations.

Synchronous invocation (invoke()) blocks until Lambda returns a response; use for immediate results. Asynchronous invocation (invokeAsync()) returns immediately without waiting; use for fire-and-forget patterns. AWS SDK for Java 2.x supports both via LambdaClient and LambdaAsyncClient.

Yes. AWS SDK for Java 2.x provides operations to create, update, and delete Lambda layers and aliases. Manage layer versions, version aliases, and function routing through dedicated requests, enabling full programmatic control of Lambda configurations.
