Dear Spring community,

Today I'm excited to share with you news that Spring Integration extension project for AWS and AWS Kinesis Binder for Spring Cloud Stream have finally been moved to AWS Java SDK v2, their respective milestones 3.0.0-M2 & 4.0.0-M1 are available from Spring Milestone repository.

I cannot tell that this was a pleasant work to do because it has turned to be not just a plain dependencies upgrade and namespace renaming. The whole AWS SDK API was changed to more modern Java style, including CompletableFuture composition and Stream API, lambda-style configuration, generated builders etc. They have even Reactive Streams support! Some options have been removed and some added. So, even if Spring Integration channel adapters are high enough API for end-users, they still suffered many breaking changes with these new generations.

Some highlights of these milestone:

• Of course, first of all the latest AWS SDK 2.20.32
• Upgrades to Spring Cloud AWS 3.0.0 with its new SQS listener API
• XML configuration removal. Right, this is unusual for Spring backwards compatibility, but Spring Cloud AWS did that already and there is no any Spring Cloud projects providing and XML support.
• Our own DynamoDbLockRegistry implementation with a proper TTL support.
• KCL channel adapter now relies on a new Enhanced Fan-Out Consumer.
• All outbound channel adapters are async by default and leverage a CompletableFuture support from their super AbstractMessageProducingHandler class.
• The Glue Schema support has been exposed in KCL and KPL channel adapters.
• The Kinesis Binder does not support DynamoDB Streams Adapter any more. There is no its implementation for SDK v2 and general AWS recommendation is to use Kinesis enabled on the table to captures data changes.

See READMEs of these projects on GitHub for more information.

We are probably going to GA in a couple weeks, so don't hesitate to give them a try and come back with any feedback or contribution!

Cheers, 
Artem
