Ruby bindings

[j-a-m-l]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
We (me and @kou ) want to implement Ruby bindings for DataFusion.

Describe the solution you'd like
We think that after #1113, we could use the C API to create the Ruby bindings GObject introspection, the same way that Red Arrows does.

Describe alternatives you've considered
Rutie seems simpler, but exposing the C API could be much more beneficial to allow other language bindings.

similarly I'm thinking of #1108 and for the moment putting the code here

[j-a-m-l]

We're going to follow a similar approach: first create a PoC and then, integrate it here if it is accepted.

I've seen @jimexist that you've created an issue for upgrading to edition 2021. (edited) I'd like to start with it directly, but it is simpler to just use 2018.

I've created a repo: https://github.com/j-a-m-l/datafusion-ruby

In the branch rutie I've also started to try Rutie to integrate Rust in Ruby. Currently the example is very simple and does not include any DataFusion code, but it looks a lot easier than creating the C bindings first.

see #1174 @j-a-m-l

nice work @j-a-m-l, we took the same approach for delta-rs's ruby binding as well :)

Thanks @jimexist and @houqp for your comments.

My idea is trying Rutie a little more before deciding if it's a simpler approach than creating the C bindings first and then using them to build the Ruby bindings.

There is another library for ruby bindings to rust - not sure which is more advanced

Just to clarify: I can't be involved in this binding, since my current employer is not interested and I don't have enough free time to do it.

@andygrove Could you create https://github.com/datafusion-contrib/datafusion-ruby and give me admin permission? We can implement Ruby bindings based on https://github.com/datafusion-contrib/datafusion-c .

@kou I have created the repo and sent you an invite.

Thanks! Confirmed.

I close this issue. We can use https://github.com/datafusion-contrib/datafusion-ruby for further discussion if it's needed.
