Following are the sample query to get the count using the aggregate function.

  "size" : 0,
  "query" : {
    "term" : {
      "columnid" : {
        "value" : 1,
        "boost" : 1.0
      }
    }
  },
  "_source" : false,
  "stored_fields" : "_none_",
  "aggregations" : {
    "groupby" : {
      "composite" : {
        "size" : 10,
        "sources" : [
          {
            "14" : {
              "terms" : {
                "field" : "columnid",
                "missing_bucket" : true,
                "order" : "asc"
              }
            }
          }
        ]
      }
    }
  }
}

Also use can translate your SQL query into kibana query using following query-

 POST _xpack/sql/translate
    {
       "query": "SELECT COUNT(*), columnid FROM Indexname WHERE columnid=1 group by columnid ",
       "fetch_size": 10
    }
