    • failOnMissingColumn

      public CarpetParquetReader.Builder<T> failOnMissingColumn(boolean failOnMissingColumn)
      Feature that determines whether encountering of missed parquet column should result in a failure (by throwing a RecordTypeConversionException) or not. Feature is enabled by default.
      Parameters:
      failOnMissingColumn -
      Returns:
      Carpet Reader Builder

    • strictNumericType

      public CarpetParquetReader.Builder<T> strictNumericType(boolean strictNumericType)

    • failOnNullForPrimitives

      public CarpetParquetReader.Builder<T> failOnNullForPrimitives(boolean failOnNullForPrimitives)
      Feature that determines whether encountering null is an error when deserializing into Java primitive types (like 'int' or 'double'). If it is, a RecordTypeConversionException is thrown to indicate this; if not, default value is used (0 for 'int', 0.0 for double, same defaulting as what JVM uses). Feature is disabled by default.
      Parameters:
      failOnNullForPrimitives -
      Returns:
      Carpet Reader Builder
