I'm working on a project that convert parquet to JSON format through apache arrow, but got confused about it. One intuitive way is to iterate several types of `Array` directly, and construct a JSON object from it. For `PrimitiveArray` it's easy, but seems very hard for `NestArray`, since it does not provide any `Iterator` interface to get an `Struct`, `List`, `Map`, but only the underlying stored array. I have investigate the examples and documents to solve this problem but got no result. To conclude, is there interface to iterate nested structure in row-oriented style, instead of operate on the underlying array? Or existed interface to convert arrow array to JSON format?
