> optimize presto query time for dictionary include string column.
>
> problem: currently, for each query, presto carbon creates dictionary block
> for string columns.
> This happens for each query and if cardinality is more , it takes more time
> to build. This is not required. we can lookup using normal dictionary lookup.
