> Just like parquet format, ORC has a large group of fans in Bigdata area, it 
> has better performance than parquet in some use cases.
>  But there is a problem in python is that it doesn't have the standard write 
> function.
> Seems the ORC team itself maintains the standard C++ 
> code([https://github.com/apache/orc/tree/master/c%2B%2B]) , so I think it 
> won't take too much effort to integrate into Arrow(C++) and build the hook 
> for python.
