Marios Trivyzas commented on FLINK-26098:
-----------------------------------------
It also works with the new approach of creating a
{{{}StreamTableEnvironment{}}}:
{noformat}
StreamExecutionEnvironment streamExecutionEnvironment =
StreamExecutionEnvironment.getExecutionEnvironment();
Configuration configuration = new Configuration();
configuration.set(TABLE_EXEC_SOURCE_IDLE_TIMEOUT, Duration.ofSeconds(100));
EnvironmentSettings settings =
EnvironmentSettings.newInstance()
.inStreamingMode()
.withConfiguration(configuration)
.build();
StreamTableEnvironment streamTableEnvironment =
StreamTableEnvironment.create(streamExecutionEnvironment,
settings);{noformat}
> TableAPI does not forward idleness configuration from DataStream

> Affects Versions: 1.15.0, 1.14.3
> 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.
