Hello everyone, I have a question regarding the StructType and its corresponding StructArray in Apache Arrow.
>From the documentation, I understand that StructType is categorized as a NestedType, which is a data type whose full structure depends "on one or more other child types". This implies that there should be at least one child type. However, I've noticed that there are no explicit checks for this requirement in the StructType constructor. Additionally, I've come across instances in the code where StructArray is constructed without children, such as in this example: link to code ( https://github.com/apache/arrow/blob/main/cpp/src/arrow/record_batch.cc#L292 ). My question is: Does the library officially support a StructType that does not have any children? Best regards, Artem
