case class DeltaParquetFileFormat(protocol: Protocol, metadata: Metadata, nullableRowTrackingFields: Boolean = false, optimizationsEnabled: Boolean = true, tablePath: Option[String] = None, isCDCRead: Boolean = false) extends ParquetFileFormat with Product with Serializable

A thin wrapper over the Parquet file format to support

  • columns names without restrictions.
  • populated a column from the deletion vector of this file (if exists) to indicate whether the row is deleted or not according to the deletion vector. Consumers of this scan can use the column values to filter out the deleted rows.
