The AWS SDK for Java (Version 1.x) has been connecting JVM based applications to AWS services since 2010. However, the JVM eco-system has changed a lot in the last 7 years. Based on a lot of customer feedback, we recently launched a developer preview of Version 2.0 of the AWS SDK for Java, which has been completely re-written from the core HTTP layer to the service clients. In this session, we'll get under the covers of the code-base to see how we've been able to get over 100,000 TPS from a single client instance during initial testing. We'll also go over some of the many new features and highlight some of the major differences with 1.x including: pluggable HTTP, non-blocking I/O, enhanced pagination, immutability and more.
