########## flink-table/flink-table-runtime/src/main/java/org/apache/flink/table/runtime/operators/join/lookup/keyordered/Epoch.java: ########## @@ -72,6 +74,7 @@ public void setOutput(Consumer<StreamElementQueueEntry<OUT>> outputConsumer) { public void decrementCount() { ongoingRecordCount--; + Preconditions.checkState(ongoingRecordCount >= 0); Review Comment: Current implementation works in the mailbox thread and it is not designed to work for multi-threads. Besides, this structure would be removed. The AsyncExecutionController in flink-runtime would be integrated into stream opeator as a generialized framework. Based on this, I tend to have the current delta join operator and async key ordered lookup operator temporarily rely on this structure without deeper refactoring, since a more comprehensive refactoring will occur in the near future. -- This is an automated message from the Apache Git Service.
