> Affects Versions: 2.0.0

> Like {{increment}}/{{append}}, the {{checkAndPut}}/{{checkAndDelete}} operation is non-idempotent, so that the client may get incorrect result if there are retries, and such incorrect result may lead the application enter an error state. A possible solution is using nonce for checkAndMutate operations, discussions and suggestions are welcomed.
