// Cannot find what should I use instead of ReadSupport, ReadSupport, DataSourceReader
// if instead of ReadSupport we have to use now Scan then what happened to method createReader?

  override def createReader(options: DataSourceOptions): DataSourceReader = new GeneratingReader()

class GeneratingReader() extends DataSourceReader {
  override def readSchema(): StructType = {...}
