我们使用kafka connect jdbc连接器从oracledb中使用jdbcsource连接器的表中获取数据，并通过一个主题将其上载到postgresdb中使用jdbcsink连接器的目标表中。在执行此活动时，我们能够从源获取数据并将其更新到目标表。但源表中的记录数与目标数据库中的记录数不匹配。有没有办法查一下

1.  the data fetched by the source connector and uploaded in the topic 
2.  Any way to track the records and identify why its not uploaded in the target table.  
3. How to identify the records that has not been uploaded into the target based on the log details.
