Now Available – Developer Preview of AWS SDK for Java 2.0

The AWS Developer Tools Team has been hard at work on the AWS SDK for Java and is launching a Developer Preview of version 2.0 today.

This version is a major rewrite of the older, 1.11.x codebase. Built on top of Java 8 with a focus on consistency, immutability and ease of use, the new SDK includes frequently requested features such as support for non-blocking I/O and the ability to choose the desired HTTP implementation at runtime. The new non-blocking I/O support is more efficient than the existing, thread-based implementation of the Async variants of the service clients. Each non-blocking request returns a CompletableFuture object.

The version 2.0 SDK includes a number of changes to the earlier APIs. For example, it replaces the existing mix of client constructors and mutable methods with a consistent model based on client builders and immutable clients. The SDK also collapses the disparate collection of classes used to configure regions into a single Region class, and provides a new set of APIs for streaming.

The SDK is available on GitHub. You can send public feedback by opening GitHub issues and you can also send pull requests in the usual way.
