According to the article, the most interesting feature compared to Jupyter is no hidden state - if you delete a cell, the variables it set are gone. Also, you c

  The SQL support is done through Spark, so it's not particularly novel – Zeppelin for example supports SQL similarly. We've talked about adding a more general SQL interpreter, though. Happy to hear any suggestions about it!

    Do you know of any generalized SQL interpreter that allows push-downs to the underlying engine where possible, but can also arbitrate compute resources to post-push down operations. Eg: such as merging disparate result-sets or make up for the lack of features from the underlying engines. Closest thing that comes to mind is something like Apache Drill, which coincidentally also uses Apache Calcite as the SQL interpreter. Also wondering why I would use this over Zeppelin which can support other interpreters like Flink?

  > Also, you can mix languages Interesting. Judging by that it seems to be implemented with a JVM language and a screenshot shows "Scala" as a supported language, I'm guessing at least all the JVM languages are supported (personally hope for Clojure) but can't seem to find a list of supported languages anywhere in the post or on the website. What languages are supported by Polynote?

    Looks like just Scala and Python right now: https://github.com/polynote/polynote/blob/08f0751138e2991cf77e711344c8edcd8a976929/polynote-kernel/src/main/scala/polynote/kernel/interpreter/CoreInterpreters.scala https://github.com/polynote/polynote/blob/08f0751138e2991cf7...

    Currently just Scala and Python (via jep). Looking to add more (probably starting with Java and clojure) but haven't had time yet. There's just two of us working on it so far. PRs welcome!

      Have you looked at GraalVM to bring in more languages?
      • type_enthusiast 7y ago
        Yep, we will be adding a plug-in to support Graal languages (little bit of learning to do on Graal first). We didn't want to make the project depend on Graal, though, because it's a pretty small segment of users (and we're not using it on our team at this point).

          To verify, will this plugin allow external parties to add support to Polynote for more esoteric languages?
          • type_enthusiast 7y ago
            I don't want to over-promise anything given that I still have some reading to do about Graal's inner workings. But even given the interpreter side, there's also some plumbing to do (e.g. Monaco integration) that we haven't thought out yet. It's still in its infancy, and we'll need some help to be able to add stuff like this.

              Get in touch with me if you want any help - I have experience in embedding Graal.

  R notebooks do a lot of this stuff reasonably well, too. But then you have R as the primary language (other langs are well supported though). As ever, the best answer is the Notebooks Are Bad, Actually
