> Cell level encryption can do finer-grained encryption than modular 
> encryption(Parquet-1178) or file encryption. The idea is only some fields 
> inside the column are encrypted based on a filter expression. For example, a 
> table with column a, b, c.x, c.y, d, we can encrypt column a, c.x where d == 
> 5 and c.y > 0.
