@huaxingao Thank you for your detail response. Actually, `Timestamp` in spark has the range '0001-01-01T00:00:00.000000Z, 9999-12-31T23:59:59.999999Z', see `org.apache.spark.sql.types.TimestampType`(8 bytes), and the relative date type seems should be `datetime` (8 bytes) in mysql, not the timestamp, only 4 bytes and have a smaller range '1970-01-01 00:00:01.000000' to '2038-01-19 03:14:07.999999'. In real test： We can not insert '1111-01-01 00:00:01' from spark into TIMESTAMP column of mysql currently because of out of range. but we can insert the former '1111-01-01 00:00:01'into DATETIME column of mysql for `datetime` contains the range of `timestamp` in mysql.
