AWS Lambda, a serverless compute service by Amazon Web Services (AWS), has recently announced support for using custom serializers with Java runtimes. This feature allows developers to replace the default Java object serialization library with a customer-defined serializer, enabling them to adapt their Lambda functions to cases where the incoming event format is not compatible with the default Lambda serializer.
This new capability is supported in all current Lambda managed runtimes and container base images for Java, providing greater flexibility and control for developers building serverless applications on AWS.
For more information on how to build, test, and deploy custom Java runtimes for Lambda functions, check out the AWS blog post: https://aws.amazon.com/blogs/compute/build-a-custom-java-runtime-for-aws-lambda/
