From the current benchmark, seems the performance has not obvious
improvement, compared with the vectorized Hive ORC reader #13775.
Maybe with more efficient batch approach as @cloud-fan suggested, it can
perform better.
Besides performance, getting rid of Hive dependency on ORC datasource is a
great advantage for this.
