Is it okay to use aws javasdk v2 and v1 together?

[devsungmin]

I am developing an application using Dynamo DB in Spring boot 3.0.5 version.

The Spring Data Project does not officially support Dynamo DB.
So I bring and use the released as an open source project, but for that open source project use the AWS Java SDK V1.

Many example codes released on the Internet are based on the SDK V1, but there are many difficulties in developing based on aws official documents for the V2, and I don't think it's possible to develop it with the V2, is the designed to be used with V1?

Yes, you can use Java SDK v1 and v2 side-by-side.

We have a page in the Developer Guide that shows how to set the dependencies in the pom file:
https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/migration-side-by-side.html

Many example codes released on the Internet are based on the SDK V1, but there are many difficulties in developing based on aws official documents for the V2, and I don't think it's possible to develop it with the V2, is the designed to be used with V1?

If you are using a service client in v1 (like S3 or Dynamo DB), all clients should have an equivalent in v2, you should be able to call any service API from v1 or v2.
If you are using a high-level library in v1 (like TransferManager or DynamoDB Mapper), the equivalent high-level libraries in v2 were completely rewritten and will require some code adjustments to fit the v2 syntax. Some high-level libraries were not released yet in v2, you can search for feature requests trackers in the Github issue list.

Can you elaborate on the difficulties you have encountered when developing using Java SDK v2? We are genuinely interested, so we can improve the documentation around v1 to v2 migration.

Thank you @debora-ito 😄
Your answer was very helpful for me to develop the application.
