Summary

This release adds GraalVM support to the Serialization utility and improves the Batch Processing utility allowing you to pass a custom Executor giving you more control over the resources used by the batch operations.

⭐️ Thanks to @visheshruparelia for their first contribution to Powertools for AWS! And thanks to @jreijn for adding GraalVM support to the serialization module.

Add support for batch execution in parallel with custom Executor

Docs

This feature enhances the batch processing capabilities by allowing parallel execution with a custom Executor. This allows you to customize the resources used by the batch operations, such as providing your own thread pool giving you more control over the degree of concurrency.

Here's an example of how to use a custom executor for parallel batch processing:

public class SqsBatchHandler implements RequestHandler<SQSEvent, SQSBatchResponse> {

 private final BatchMessageHandler<SQSEvent, SQSBatchResponse> handler;
 private final ExecutorService executor;
    
 public SqsBatchHandler() {
    handler = new BatchMessageHandlerBuilder()
                    .withSqsBatchHandler()
                    .buildWithMessageHandler(this::processMessage, Product.class);
                    executor = Executors.newFixedThreadPool(2);
 }
    
 @Override
 public SQSBatchResponse handleRequest(SQSEvent sqsEvent, Context context) {
    // New feature: custom executor can now be passed as a method argument for parallel processing
    return handler.processBatchInParallel(sqsEvent, context, executor);
 }
    
 private void processMessage(Product p, Context c) {
    // Process the product
 }
}
