No, this could be useful for that work in data. I just started with connectivity and few methods in repository implemented and switched to something else so I will definitely be able to use this later.

Any plans for an EnhancedDynamoDbClient in Micronaut? https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/dynamodb-enhanced-client.html

We just do it in a library so the Beans are available for use. I think we had to do something custom with @secondary constructors to make it work with micronaut test resources as well. I can follow up on this

I see this is the current solution, excluding doing yourself, https://micronaut-projects.github.io/micronaut-aws/latest/guide/#thirdPartyLibraries

thanks for mentioning @scprek. The v2 implementation works nicely with EnhancedDynamoDbClient and you can use Integration Testing library to start up a Localstack under the hood without any additional configuration.
