   [Druid filtered 
aggregator](https://druid.apache.org/docs/latest/querying/aggregations.html#filtered-aggregator)
  may be help you . I think it can be parsed to native query like below:    
   
   ```json 
   {
       "queryType":"queryType",
       ....
       "aggregations":[
           {
               "type":"filtered",
               "filter":{
                   "type":"selector",
                   "dimension":"column_A",
                   "value":"value_one"
               },
               "aggregator":{
                   "type":"longSum",
                   "fieldName":"column_B",
                   "name":"sum_B"
               }
           },
           {
               "type":"filtered",
               "filter":{
                   "type":"selector",
                   "dimension":"column_A",
                   "value":"value_two"
               },
               "aggregator":{
                   "type":"longSum",
                   "fieldName":"column_D",
                   "name":"sum_D"
               }
           }
       ]
   }
   ```
