We were trying the Presto with carbon data and in the code currently
Carbondata is decoding the dictionary values into actual values as soon as
the data is read from Carbondata. I think if we do a lazy decode of
dictionary values after aggregation it will make the queries faster.
Please let me know if anybody have some thoughts about decoding it when
calculating the final results.

Thanks and regards
