Description

Need the user interface for user to define the TopN. User need to selecting: 1) the metrics column; 2) the literal column;

This is a sample:

{
    "name" : "TOP_SELLER",
    "function" : {
      "expression" : "TOP_N",
      "parameter" : {
        "type" : "column",
        "value" : "PRICE",
        "next_parameter" : {
          "type" : "column",
          "value" : "SELLER_ID",
          "next_parameter" : null
        }
      },
      "returntype" : "topn(100)"
    }
  }
