This isn't as much a feature as an internal improvement. The aws-sdk-go-v2 is a newer iteration of the design of the AWS SDK for Go.
Use Case(s)
aws-sdk-go-v2 improves upon a number of deficiencies in aws-sdk-go. This has tangible improvements -- for instance, it properly retries a much wider range of request errors (for example: SlowDown from S3, connection resets from KMS). This will reduce the number of spurious backup failures within Vitess. The API change is relatively straightforward and PlanetScale has found that it is has been drop-in compatible from a performance and functionality perspective for its internal backup storage implementation.
