Hi, this is a bug. https://github.com/apache/seatunnel/blob/dev/seatunnel-connectors-v2/connector-clickhouse/src/main/java/org/apache/seatunnel/connectors/seatunnel/clickhouse/source/ClickhouseSourceSplitEnumerator.java#L77 Sometimes the reader register to enumerator at same time, so multiple reader receive query task. We need add a lock. And looks it's not support `SupportParallelism`, the query can only run on 1 reader. ``` if (assigned < 0 ){ assigned = subTaskId; // so next time other reader won't be assign read task. Means not support `SupportParallelism` } ``` cc @Hisoka-X , Please correct me if I am wrong. -- This is an automated message from the Apache Git Service.
