* Warning: Adaptive retry mode assumes that the client is working against a single resource (e.g. one
* DynamoDB Table or one S3 Bucket). If you use a single client for multiple resources, throttling or outages
* associated with one resource will result in increased latency and failures when accessing all other resources via
* the same client. When using adaptive retry mode, we recommend using a single client per resource.
