- record writer for object needs to find codec - Change to use a pre-defined codec or implement Surface.ofClass(cl) - Or create our own ParquetRecordWriter.write[A](obj:A) and build the Surface with compile-time macro (inline method) - but this will not work for nested map types: `Map("nested" -> NestedCls(....))`
Map("nested" -> NestedCls(....))
