Support different naming strategies for DynamoDB attributes in enhanced client #5765
Description
Describe the feature
My understanding is, by default, the enhanced DynamoDb client will assume your attributes are named like your variables which happen to be camel case. If you want your createdAt field to be stored with attribute name created_at you either have to use an annotation to overwrite this field individually or use the TableSchema builder to explicitly define all your fields attribute names.
I’d prefer something like Jackson where you can set the naming strategy to be camel case, upper camel case, snake case, kebab case, etc.
Use Case
This would be useful as I don’t think there is a standard for attribute name style and the AWS blog / docs are also inconsistent (but consistent within an example), but the sdk forces you into something if you don’t want to write more annotations.
Proposed Solution
The TableSchema.fromClass or fromBean method accepts configuration for what naming strategy to use, similar to configuring Jackson’s ObjectMapper.
