Hi @michaelbrewer, thank you for the feature request. We'd definitely love to provide the equivalent of DynamoDbMapper in the future. I'll leave this request open to allow others to 👍 upvote and that may help us with prioritization.

Additional context from #76:

We might be able to do this as a compiler plugin and generate rather optimized code so that we don't have to rely on annotation processing (which I believe is JVM only at the moment) OR on reflection capabilities.

See a good high level overview of considerations from rust SDK: awslabs/aws-sdk-rust#70

Another possibility might be to leverage kotlinx.serialization. I haven't looked into it too thoroughly yet, but it seems like it would be straightforward to convert classes to and from DynamoDB Json.

Any update on this issue?

ianbotsf commented 1 year ago

We have no new updates to share at this time. Providing a high-level DynamoDB client remains on our roadmap but will likely not be prioritized until the underlying SDK itself (including the low-level DynamoDB client) is stable and released as 1.0.
