Description

Relevant issue:https://github.com/apache/arrow/issues/2287

 

I'm creating a struct with the following schema in arrow: https://pastebin.com/Cc8nreBP
 

When I try to convert that table to a .parquet file, the file gets created with a valid schema (the one I posted above) and then throws this exception: "lemented: Level generation for Struct not supported yet".

 

Here's the code: https://ideone.com/DJkKUF

 

Is there any way to write arrow table of structs to a .parquet file in cpp?
