> When writing to the target table fails for some reason, for example, the target table does not exist.
> The internal call sequence of JdbcOutputFormat is:
> JdbcOutputFormat#flush(throws IOException) --> JdbcOutputFormat#close --> JdbcOutputFormat#flush(throws RuntimeException).
> Will not call the close method of the database connection, this will cause the number of database connections to continue to rise and reach the limit.
