That can lead to the halt of processing if all sources are idle > because {{WatermarkAssignerOperator}} [1] will never set a channel to active > again. The only way to mitigate the problem is to explicitly configure the > idleness for table sources via {{table.exec.source.idle-timeout}}. > Configuring this value is actually not easy because creating a > {{StreamExecutionEnvironment}} via {{create(StreamExecutionEnvironment, > TableConfig)}} is deprecated. > [1] > https://github.com/apache/flink/blob/master/flink-table/flink-table-runtime/src/main/java/org/apache/flink/table/runtime/operators/wmassigners/WatermarkAssignerOperator.java#L103 -- This message was sent by Atlassian Jira (v8.20.1#820001)
