### 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 ### Background When using Apache SeaTunnel with MySQL CDC as the source, parallelism > 1, and multiple sinks (e.g., OceanBase and MySQL), an intermittent issue was observed where the `Write Count So Far` in the Job Progress Information consistently showed 0, despite data being successfully written to the target databases. ### Symptom ``` Job Progress Information *********************************************** Job Id : 1064431526965411841 Read Count So Far : 1343176 Write Count So Far : 0 Average Read Count : 6539/s Average Write Count : 0/s Last Statistic Time : 2026-01-16 14:33:55 Current Statistic Time : 2026-01-16 14:34:55 *********************************************** ``` ### Reproducibility - Not consistently reproducible - Occurs in multi-sink scenarios ### Json example ```json SourceReaders JSON: [ {"tags":{"jobId":"1065907369516466177","taskGroupId":"3","address":"[localhost]:5801","service":"TaskExecutionService","taskGroupLocation":"TaskGroupLocation{jobId=1065907369516466177, pipelineId=1, taskGroupId=3}","member":"f8c47ea3-88f6-4cfa-a299-79ab8f4ea9f3","taskName":"SourceSeaTunnelTask","taskID":"1000300000001","pipelineId":"1"},"metric":"SourceReceivedCount","value":0,"timestamp":1768896964860}, {"tags":{"jobId":"1065907369516466177","taskGroupId":"2","address":"[localhost]:5801","service":"TaskExecutionService","taskGroupLocation":"TaskGroupLocation{jobId=1065907369516466177, pipelineId=1, taskGroupId=2}","member":"f8c47ea3-88f6-4cfa-a299-79ab8f4ea9f3","taskName":"SourceSeaTunnelTask","taskID":"1000200000000","pipelineId":"1"},"metric":"SourceReceivedCount","value":232003,"timestamp":1768896964860}] SinkWriters JSON: [ {"tags":{"jobId":"1065907369516466177","taskGroupId":"3","address":"[localhost]:5801","service":"TaskExecutionService","taskGroupLocation":"TaskGroupLocation{jobId=1065907369516466177, pipelineId=1, taskGroupId=3}","member":"f8c47ea3-88f6-4cfa-a299-79ab8f4ea9f3","taskName":"TransformSeaTunnelTask","taskID":"1000300010001","pipelineId":"1"},"metric":"SinkWriteCount","value":0,"timestamp":1768896964860}, {"tags":{"jobId":"1065907369516466177","taskGroupId":"3","address":"[localhost]:5801","service":"TaskExecutionService","taskGroupLocation":"TaskGroupLocation{jobId=1065907369516466177, pipelineId=1, taskGroupId=3}","member":"f8c47ea3-88f6-4cfa-a299-79ab8f4ea9f3","taskName":"TransformSeaTunnelTask","taskID":"1000300020001","pipelineId":"1"},"metric":"SinkWriteCount","value":0,"timestamp":1768896964860}, {"tags":{"jobId":"1065907369516466177","taskGroupId":"2","address":"[localhost]:5801","service":"TaskExecutionService","taskGroupLocation":"TaskGroupLocation{jobId=1065907369516466177, pipelineId=1, taskGroupId=2}","member":"f8c47ea3-88f6-4cfa-a299-79ab8f4ea9f3","taskName":"TransformSeaTunnelTask","taskID":"1000200010000","pipelineId":"1"},"metric":"SinkWriteCount","value":232003,"timestamp":1768896964860}, {"tags":{"jobId":"1065907369516466177","taskGroupId":"2","address":"[localhost]:5801","service":"TaskExecutionService","taskGroupLocation":"TaskGroupLocation{jobId=1065907369516466177, pipelineId=1, taskGroupId=2}","member":"f8c47ea3-88f6-4cfa-a299-79ab8f4ea9f3","taskName":"TransformSeaTunnelTask","taskID":"1000200020000","pipelineId":"1"},"metric":"SinkWriteCount","value":232003,"timestamp":1768896964860}] ``` ### SeaTunnel Version 2.3.12 ### SeaTunnel Config ```conf env { parallelism = 2 job.mode = "STREAMING" checkpoint.interval = 5000 } source { MySQL-CDC { url = "jdbc:mysql://host:port/database1?useUnicode=true&characterEncoding=UTF-8&rewriteBatchedStatements=true" username = "username" password = "password" table-names = ["database1.table1","database1.table2"] startup.mode = "latest" plugin_output = "test" } } transform { } sink { Jdbc { driver = "com.oceanbase.jdbc.Driver" plugin_input = "test" url = "jdbc:oceanbase://host:port/database2?useUnicode=true&characterEncoding=UTF-8&rewriteBatchedStatements=true" username = "username" password = "password" compatible_mode = "mysql" database = "database2" table = "${table_name}" generate_sink_sql = true } Jdbc { driver = "com.mysql.jdbc.Driver" plugin_input = "test" url = "jdbc:mysql://host:port/database3?useUnicode=true&characterEncoding=UTF-8&rewriteBatchedStatements=true" username = "username" password = "password" database = "database3" table = "${table_name}" generate_sink_sql = true } } ``` ### Running Command ```shell bash bin/seatunnel.sh --config config/test.cfg -e local ``` ### Error Exception ```log This issue is not an exception. ``` ### Zeta or Flink or Spark Version _No response_ ### Java or Scala Version _No response_ ### Screenshots _No response_ ### Are you willing to submit PR?
