   Elasticsearch X-Pack SQL translate API also can prove this:
   
   ```
   POST /_sql/translate
   {
       "query": "SELECT k1,count(*) FROM test GROUP BY k1,k2",
       "fetch_size": 100
   }
   ```
   the result:
   
   
   ```
   {
      "size": 0,
      "_source": false,
      "stored_fields": "_none_",
      "aggregations": {
         "groupby": {
            "composite": {
               "size": 100,
               "sources": [
                  {
                     "612": {
                        "terms": {
                           "field": "k1",
                           "missing_bucket": true,
                           "order": "asc"
                        }
                     }
                  },
                  {
                     "613": {
                        "terms": {
                           "field": "k2",
                           "missing_bucket": true,
                           "order": "asc"
                        }
                     }
                  }
               ]
            }
         }
      }
   }
