   > Also potentially related to this, the way decimal data is currently read 
from parquet is hopelessly inefficient #2318. I keep meaning to fix it, but I

   Your optimization will improve the performance of reading decimal data.
   This issue may reduce unnecessary validation for generated decimal array.
