> We implement the getAndPut() and getAndDelete() by coprocessor, but there are
> a lot of duplicate effort (e.g., data checks, row lock, returned value, and
> wal). It is cool if we provide the compare-and-swap primitive.
> The draft patch is attached. Any advice and suggestions will be greatly
> appreciated.
> Thanks.
