Property column headers - Neptune Analytics

Property column headers

You can specify a column (:) for a property by using the following syntax. The type names are not case sensitive. If a colon appears within a property name, it must be escaped by preceding it with a backslash: \:. 

propertyname:type
Note

  • Space, comma, carriage return and newline characters are not allowed in the column headers, so property names cannot include these characters.

    You can specify a column for an array type by adding [] to the type: 

    propertyname:type[]

  • Edge properties can only have a single value and will cause an error if an array type is specified or a second value is specified. The following example shows the column header for a property named age of type Int. 

    age:Int

    Every row in the file would be required to have an integer in that position or be left empty. Arrays of strings are allowed, but strings in an array cannot include the semicolon (;) character unless it is escaped using a backslash (\;).
