             Summary: TableAPI does not forward idleness configuration from DataStream
                 Key: FLINK-26098
                 URL: https://issues.apache.org/jira/browse/FLINK-26098
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / API
    Affects Versions: 1.14.3, 1.15.0
            Reporter: Till Rohrmann


The TableAPI does not forward the idleness configuration from a DataStream source. 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.
