   @gregfurman I asked pretty much the same question last year 😄
   I ended up building my own [library](https://github.com/loicalleyne/bodkin) 
for schema inference, basically the json (or any structured data for that 
matter) is converted to map with mapstructure then the map is iterated over to 
build a arrow schema with a type mapping. It uses the two-pass method described 
by @joellubi, one pass to infer schema, the other to build arrow from the data.
