> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: PengLei

>
> currently, we have RowToColumnConverter for all data types except
> AnsiIntervalType
> {code:java}
> // code placeholder
> val core = dataType match {
> case BinaryType => BinaryConverter
> case BooleanType => BooleanConverter
> case ByteType => ByteConverter
> case ShortType => ShortConverter
> case IntegerType | DateType => IntConverter
> case FloatType => FloatConverter
> case LongType | TimestampType => LongConverter
> case DoubleType => DoubleConverter
> case StringType => StringConverter
> case CalendarIntervalType => CalendarConverter
> case at: ArrayType => ArrayConverter(getConverterForType(at.elementType,
> at.containsNull))
> case st: StructType => new StructConverter(st.fields.map(
> (f) => getConverterForType(f.dataType, f.nullable)))
> case dt: DecimalType => new DecimalConverter(dt)
> case mt: MapType => MapConverter(getConverterForType(mt.keyType, nullable =
> false),
> getConverterForType(mt.valueType, mt.valueContainsNull))
> case unknown => throw
> QueryExecutionErrors.unsupportedDataTypeError(unknown.toString)
> }
> if (nullable) {
> dataType match {
