[I] [Document] Why int32() offset type is used for dense union? [arrow]
andishgar opened a new issue, #46244:
URL: https://github.com/apache/arrow/issues/46244
### Describe the usage question you have. Please include as many useful details as possible.
According to the [Apache Arrow specification](https://arrow.apache.org/docs/format/Columnar.html#dense-union), the `dense union's offset type `is `int32`. However, as [noted](https://github.com/apache/arrow/pull/4781#discussion_r300780404), this limits arrays to 2 billion elements. Why not use int64, or is it possible to adopt a dual int32/int64 approach like dictionaries?
