As title, i am writing streamwork in golang-version(https://github.com/jensenojs/streamwork). but i can not find statefulOperator in anyway, everything seems fine until ch05, UsageWriter still handle with TransactionScoreEvent even what SystemUsageAnalyzer output is UsageEvent. i don't know what happened, anyone could tell me?

Thanks!

@jensenojs You are right. We are too lazy to implement the stateful operators for real. 🤦 In ch07 and ch08 there is an interface without implementation.

Oh, but you guys said that the delivery semantics would be discussed further in chapter 10. But we didn't say we were going to provide the code for chapter 10, so everything fine ( ﾟ∀ﾟ) ﾉ♡

Anyway, I know this book by knowing that it is going to be translated into Chinese (but I don't know if it is true or not), because there is sample code so I think it is a very good book, I am surprised that there are not many stars in this repository. If it really has a Chinese version of the book I would highly recommend it to students behind me in College.

@jensenojs

:D Thanks!

And, yes. I believe a group of people is translating this book into Chinese now.
