Request: Migrate DynamoDbPersistenceAdapter to AWS SDK v3 and save 60Mb

[talkingnews]

Currently, DynamoDbPersistenceAdapter has a peer dependency of aws-sdk, which install 65Mb of stuff we don't need.

Whereas the current slimline v3 version of @aws-sdk/client-dynamodb is 4.97 Mb including dependencies.
https://www.npmjs.com/package/@aws-sdk/client-dynamodb

Is anyone working on a re-write, as this library is currently the difference between my skill package being 7Mb or 70Mb!

agree this is a pain point. Will try to bump it up on the priority list.

We definitely want to get to this. @talkingnews just so I understand, are you using any type of bundling/tree-shaking like webpack or esbuild for your skill? This might be especially helpful if you are running in AWS Lambda since the SDKs are provided by the container - bundle the skill and mark aws-sdk as external - the bundler will not include any AWS SDK code in your bundle, leaving you with a tiny JS file you can run in your Lamdba.

I understand this might not always be the right solution, so we should still create a new version of the adapter which doesn't depend on the whole AWS SDK.

@doiron this was started by @sam-goodwin and there's a linked PR. We just need to finish it up. Will discuss during sprint planning.

Is this issue/feature-request still relevant?
We are working on prioritization of relevant issues and cleanup of rest. If we don’t hear back in 2 weeks, we will assume that the issue is not relevant and we will close it.
