I have the same use case. I am using https://github.com/datafusion-contrib/datafusion-functions-json and the arrow_json writer. Would adding support for encoding unions to the arrow_json be sufficient? I imagine it would be an untagged union and just flatten away the union itself. As the json functions repo produces a Sparse union that would work well for that case. We could either error for Dense unions like we do today or agree on a way to flatten the union adding explicit nulls. Thoughts? I could put up a PR for sparse unions if we agree its a good solution. -- This is an automated message from the Apache Git Service.
