 With the [announcement](https://aws.amazon.com/blogs/developer/announcing-availability-of-the-aws-crt-http-client-in-the-aws-sdk-for-java-2-x/) of the `aws-crt-client` a new http client has been released, which offers faster SDK startup time and smaller memory footprint. 
 
 Unfortunately, replacing the `url-connection-client` dependency with the `aws-crt-client` will not immediately improve the lambda cold start performance and memory footprint,
