### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened MySql-CDC Source,Clickhouse Sink.bulk_size is not set(defaule 20000), the data source has 50,000 rows of data, but clickhouse only writes 40,000 rows. Waiting for the trigger checkpoint did not write the remaining 10,000 rows of data. Set bulk_size to 1, all data will be written to clickhouse ### SeaTunnel Version 2.3.1 ### SeaTunnel Config ```conf env { execution.parallelism = 5 job.mode = "STREAMING" } source { MySQL-CDC { result_table_name = "mq" #server-id = 5656 base-url = "jdbc:mysql://hadoop12:3306/dbname" driver = "com.mysql.cj.jdbc.Driver" username = "xx" password = "xxx" table-names = ["xx.xxx"] startup.mode = "earliest" debezium { snapshot.mode = "never" decimal.handling.mode = "double" } } } sink { clickhouse { source_table_name = "mq" host = "localhost:8123" username = "xx" password = "xxx" database = "db2" table = "xx" # bulk_size = 1 # cdc options primary_keys = "id" support_upsert = true allow_experimental_lightweight_delete = true } } ``` ### Running Command ```shell seatunnel.sh -c cktest.conf -e local ``` ### Error Exception ```log None ``` ### Flink or Spark Version _No response_ ### Java or Scala Version jdk 1.8 ### Screenshots   ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
