Metadata

Description

The aggregator requires account metadata. This parameter is a path to a json file that represents that metadata. It is used to understand the input file schema.

#	Field	Description
1	name	Name of the column
2	position	Column number
3	typ	It should match with the input file data type.Data type possible values: I32,F32,I64,F64,String.I32 for Number in range (-2,147,483,648 to 2,147,483,647). I64 for number in range (-1e19 to 1e19). F32 for less precise and F64 for more precise decimal number. Note: for date, it should be i64.

Example

{
  "fields": [
    {
      "name": "gl_cd",
      "position": 1,
      "typ": "String"
    },
    {
      "name": "branch_cd",
      "position": 2,
      "typ": "String"
    },
    {
      "name": "dr_bal",
      "position": 3,
      "typ": "F64"
    }
  ]
}

In the above example, dr_bal is the name of the column present in the 3rd position of the input file and is of decimal type.
