   ### Search before asking
   
   - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
   
   
   ### Description
   
   Currently, Doris computes keys hash and insert tuple to correct position in hash table for each tuple. I think a more effective way is to compute hash values for each column and then insert then to hash table. It will benefit more from vectorized engine.
   
   ### Solution
   
   use vectorized computation for hash values in hash aggregation
