Data Generator

Utility to generate fake data based a defined schema. The schema syntax is inspired by the EdgeDB data model syntax.

User will define the schema, a .sdl as follows;

model test_data {
    col1: int(1 -> 100),
    col2: str {
        default   := one_of('my_name', 'another_str')
    },
    col3: currency(1 until 200) {
        provider := @currency,
        default  := '$3.40'
    },
    col4: array<str> {
        providers := [ @name, @business ],
        default   := many_of('s1', 's2', 's3'),
        maxlength := 10
    },
    col5: {datetime|date},
    col6: uuid,
    configuration {
        lines       := 1_000,
        format      := csv
        description := "Lorem ipsum ipsum..."
    }
}

Supported Types

The supported types are as follows;

  • int or int(0 until 10) or int(0 -> 10): where 0 until 10 represents the required rannge that the generated number must not exceed
  • float(0 until 10): floating point number
  • str: a combination of alphanumeric characters
  • bool: a true or false
  • uuid: this represents a uuid
  • array<str|int|float>: array of scalar types. It should be noted that arrays cannot contain other arrays
  • currency or currency(0..10): currency value. Also, when a boud e.g. (0..10) is specified, the generator only generates currency within this given range.
  • date|datetime: date and datetime field

It should be noted that arrays cannot contain other arrays.
