### Search before asking - [X] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened When we are using Postgres-CDC as a Source and RabbitMq, JDBC and Console as Sink we are getting duplicate data in case of RabbitMq and Console. This issue occurs only when we receive update record from CDC Source. Is there any way to avoid the duplicates when we receive Updates from CDC ? This doesn't happen for JDBC because as per the codebase the **UPDATE_BEFORE** ROW_KIND transaction is being skipped.  ### SeaTunnel Version 2.3.8 ### SeaTunnel Config ```conf env { execution.parallelism = 1 job.mode = "STREAMING" checkpoint.interval = 5000 read_limit.bytes_per_second=7000000 read_limit.rows_per_second=400 } source { Postgres-CDC { result_table_name = "employees" username = "postgres" password = "password" database-names = ["postgres"] schema-names = ["public"] slot.name = "employeesslot" table-names = ["postgres.public.employees"] base-url = "jdbc:postgresql://localhost:5432/postgres" startup.mode = "latest" } } transform { Filter { source_table_name = "employees" result_table_name = "employeesfieldtransform" include_fields = [id] } } sink { Jdbc { source_table_name = "employees" url = "jdbc:postgresql://localhost:5432/postgres" driver = org.postgresql.Driver user = postgres password = "password" database = postgres table = "public.employees" generate_sink_sql = true } RabbitMQ { source_table_name = "employeesfieldtransform" host = "localhost" port = 5672 virtual_host = "/" username = "guest" password = "guest" queue_name = "test" durable = "true" exclusive = "false" auto_delete = "false" rabbitmq.config = { requested-heartbeat = 10 connection-timeout = 10 } } Console { source_table_name = "employeesfieldtransform" } } ``` ### Running Command ```shell ./bin/seatunnel.sh --config config/employees.template --async -n employeessync ``` ### Error Exception ```log No Exception or Error. But we see duplicate entries as below.
