Re: [CONNECT] New Clients for Go and Rust
Hi folks, Thanks a lot to the help form Hykjin! We've create the https://github.com/apache/spark-connect-go as the first contrib repository for Spark Connect under the Apache Spark project. We will move the development of the Golang client to this repository and make it very clear from the README file that this is an experimental client. Looking forward to all your contributions!

Re: [CONNECT] New Clients for Go and Rust
I think it makes sense to split this discussion into two pieces. On the contribution side, my personal perspective is that these new clients are explicitly marked as experimental and unsupported until we deem them mature enough to be supported using the standard release process etc. However, the goal should be that the main contributors of these clients are aiming to follow the same release and maintenance schedule. I think we should encourage the community to contribute to the Spark Connect clients and as such we should explicitly not make it as hard as possible to get started (and for that reason reserve the right to abandon). How exactly the release schedule is going to look is going to require probably some experimentation because it's a new area for Spark and it's ecosystem. I don't think it requires us to have all answers upfront. > Also, an elephant in the room is the future of the current API in Spark 4 and onwards. As useful as connect is, it is not exactly a replacement for many existing deployments. Furthermore, it doesn't make extending Spark much easier and the current ecosystem is, subjectively speaking, a bit brittle. The goal of Spark Connect is not to replace the way users are currently deploying Spark, it's not meant to be that. Users should continue deploying Spark in exactly the way they prefer. Spark Connect allows bringing more interactivity and connectivity to Spark. While Spark Connect extends Spark, most new language consumers will not try to extend Spark, but simply provide the existing surface to their native language. So the goal is not so much extensibility but more availability. For example, I believe it would be awesome if the Livy community would find a way to integrate with Spark Connect to provide the routing capabilities to provide a stable DNS endpoint for all different Spark deployments. > [...] the current ecosystem is, subjectively speaking, a bit brittle. Can you help me understand that a bit better? Do you mean the Spark ecosystem or the Spark Connect ecosystem?

Re: [CONNECT] New Clients for Go and Rust
It might be a good idea to have a discussion about how new connect clients fit into the overall process we have. In particular: * Under what conditions do we consider adding a new language to the official channels? What process do we follow? * What guarantees do we offer in respect to these clients? Is adding a new client the same type of commitment as for the core API? In other words, do we commit to maintaining such clients "forever" or do we separate the "official" and "contrib" clients, with the later being governed by the ASF, but not guaranteed to be maintained in the future? * Do we follow the same release schedule as for the core project, or rather release each client separately, after the main release is completed? Also, an elephant in the room is the future of the current API in Spark 4 and onwards. As useful as connect is, it is not exactly a replacement for many existing deployments. Furthermore, it doesn't make extending Spark much easier and the current ecosystem is, subjectively speaking, a bit brittle. -- Best regards, Maciej On 5/26/23 07:26, Martin Grund wrote: Thanks everyone for your feedback!

Thanks everyone for your feedback! I will work on figuring out what it takes to get started with a repo for the go client. On Thu 25.

Re: [CONNECT] New Clients for Go and Rust
Hi, Personally, I'm strongly against the second option and have some preference towards the third one (or maybe a mix of the first one and the third one). The project is already pretty large as-is and, with an extremely conservative approach towards removal of APIs, it only tends to grow over time. Making it even larger is not going to make things more maintainable and is likely to create an entry barrier for new contributors (that's similar to Jia's arguments). Moreover, we've seen quite a few different language clients over the years and all but one or two survived while none is particularly active, as far as I'm aware.

Hi, Thanks for contribution! I prefer (1). There are some reason: 1. Different repository can maintain independent versions, different release times, and faster bug fix releases. 2.

[CONNECT] New Clients for Go and Rust
Hi folks, When Bo (thanks for the time and contribution) started the work on https://github.com/apache/spark/pull/41036 he started the Go client directly in the Spark repository. In the meantime, I was approached by other engineers who are willing to contribute to working on a Rust client for Spark Connect. Now one of the key questions is where should these connectors live and how we manage expectations most effectively. At the high level, there are two approaches: (1) "3rd party" (non-JVM / Python) clients should live in separate repositories owned and governed by the Apache Spark community. (2) All clients should live in the main Apache Spark repository in the `connector/connect/client` directory. (3) Non-native (Python, JVM) Spark Connect clients should not be part of the Apache Spark repository and governance rules. Before we iron out how exactly, we mark these clients as experimental and how we align their release process etc with Spark, my suggestion would be to get a consensus on this first question. Personally, I'm fine with (1) and (2) with a preference for (2). Would love to get feedback from other members of the community! Thanks Martin
