    Reading

    with a header

    Kantan docs

    case class User(name: String, age: Int)
implicit val decoder = HeaderDecoder.decoder("fullName", "userAge")(User.apply _)
val users: SCollection[User] = scioContext.csvFile(path)

    without a header

    Kantan docs

    case class User(name: String, age: Int)
implicit val decoder = RowDecoder.ordered { (name: String, age: Int) => User(name, age) }
val csvConfiguration = CsvIO.ReadParam(csvConfiguration = CsvIO.DefaultCsvConfiguration.withoutHeader)
val users: SCollection[User] = scioContext.csvFile(path, csvConfiguration)

    Writing

    with a header

    Kantan docs

    case class User(name: String, age: Int)
implicit val encoder = HeaderEncoder.caseEncoder("fullName", "age")(User.unapply)

val users: SCollection[User] = ???
users.saveAsCsvFile(path)

    without a header

    Kantan docs

    case class User(name: String, age: Int)
implicit val encoder = RowEncoder.encoder(0, 1)((u: User) => (u.name, u.age))

val users: SCollection[User] = ???
