   @goel-skd Thanks for your interest! @HuaHuaY is working on variant encoding/decoding on arrow-cpp and we plan to reuse it for full variant type support. We are blocked until that has been finished so @zhjwpku can resume. For someone new to this project, I would suggest to get started with something smaller to get familiar with the project more quickly.

   Thanks @wgtmac . I opened 2 PR's on other issues, those are more beginner friendly I presume. :)
