When used in MapBasedRow, field in GenericRecord will be interpret as follows:

• avro schema type -> druid dimension:
• null, boolean, int, long, float, double, string, Records, Enums, Maps, Fixed -> String, using String.valueOf
• bytes -> Arrays.toString() or new String if binaryAsString is true
• Arrays -> List<String>, using Lists.transform(<List>dimValue, TO_STRING_INCLUDING_NULL)
• avro schema type -> druid metric:
• null -> 0F/0L
• int, long, float, double -> Float/Long, using Number.floatValue()/Number.longValue()
• string -> Float/Long, using Float.valueOf()/Long.valueOf()
• boolean, bytes, Arrays, Records, Enums, Maps, Fixed -> ParseException
