将下一条消息放入日志：

[2018-12-12 17:33:14,225] ERROR WorkerSourceTask{id=jdbc-source-test-0} Task threw an uncaught and unrecoverable exception (org.apache.kafka.connect.runtime.WorkerTask:177)
org.apache.kafka.connect.errors.ConnectException: Cannot make incremental queries using timestamp columns [create_time] on `test`.`test` because all of these columns nullable.

我建议它不起作用，因为此列的类型为bigint（20）。有什么解决办法吗？合流版本-5.0.1。
