Questions tagged [aws-java-sdk-2.x]

The AWS SDK for Java provides a Java API for Amazon Web Services. Using the SDK, you can easily build Java applications that work with Amazon S3, Amazon EC2, DynamoDB, and more.

Version 2.x is a major rewrite of the 1.11.x code base. Built with support for Java 8+, 2.x adds several frequently requested features, like nonblocking I/O, improved start-up performance and automatic iteration over paginated responses. In addition, many aspects of the SDK have been updated with a focus on consistency, immutability, and ease of use.
