Hi,
+----+----------+-----------------+
| id | t | tt |
+----+----------+-----------------+
| 1 | 00:00:01 | 00:00:01.000001 |
| 2 | 00:01:06 | 00:00:16.000024 |
+----+----------+-----------------+
--- tt column deserialize only '00:00:16' in int, fraction '000024' loss
Code in method deserializeDatetimeV2 of AbstractRowsEventDataDeserializer.java maybe wrong,
I refrence the another project in github named 'canal', And replace the method deserializeDatetimeV2 with someting similar in 'canal', then it worked, but i don't understand the detail, just copy and explain the similar code.
