**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] (This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*) --> https://github.com/apache/arrow-rs/pull/4239 added copy_if_not_exists support to for stores that S3-compatible stores that support it, i.e. everything other than S3. Having native support for this, and potentially other conditional operations in the future (#4879), would reduce user friction and I think unlock a number of exciting use-cases. **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> I would like to be able to configure a DynamoDB to use in a manner compatible with the [AWS DynamoDB Lock Client](https://github.com/awslabs/amazon-dynamodb-lock-client). **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> These is a [Rust port](https://docs.rs/dynamodb_lock/latest/dynamodb_lock/index.html) of the AWS lock client, but it depends on rusoto, and doesn't appear to have very strong fencing guarantees. **Additional context** <!-- Add any other context or screenshots about the feature request here. --> FYI @wjones127 -- This is an automated message from the Apache Git Service.
