Hi Till, Fan & Rong, Thanks for your feedback - I'd seen the Flink internal page but sadly, as Rong pointed out, it's pretty limited and not maintained. I'll ask on the mailing lists, but I think it would be really helpful if there were a guide for Flink developers who want to contribute to Flink, as opposed to the current documentation which is really aimed at Flink application developers (and is really pretty good). I'd happily contribute to this, but I can't find my way round the internals...
Many thanks, John ________________________________ From: Till Rohrmann <[email protected]> Sent: 04 June 2019 09:12 To: dev Subject: Re: Flink internals Hi John, unfortunately, there are no really good and up to date documents about Flink's internals. There was some discussion about updating the internals [1] but the community did decide against submitting it as a season of docs project. I agree that we should update our documentation about Flink's internals, though. At the moment, the best way about learning about Flink is the code and the user/dev ML where you can ask about concepts and how things work.
