> 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.
