Hi [~lzljs3620320] ,
master
{code:java}
/**
* Constructor for new Sources (FLIP-27).
*/
public DataStreamSource(
StreamExecutionEnvironment environment,
Source<T, ?, ?> source,
WatermarkStrategy<T> timestampsAndWatermarks,
TypeInformation<T> outTypeInfo,
String sourceName) {
super(environment,
new SourceTransformation<>(
sourceName,
new SourceOperatorFactory<>(source, timestampsAndWatermarks),
outTypeInfo,
environment.getParallelism()));
}
{code}
I want to change to the following
{code:java}
/**
* Constructor for new Sources (FLIP-27).
*/
public DataStreamSource(
StreamExecutionEnvironment environment,
Source<T, ?, ?> source,
WatermarkStrategy<T> timestampsAndWatermarks,
TypeInformation<T> outTypeInfo,
String sourceName) {
super(environment,
new SourceTransformation<>(
sourceName,
new SourceOperatorFactory<>(source, timestampsAndWatermarks),
outTypeInfo,
environment.getParallelism()));
this.isParallel = true;
}
{code}
What do you thank of ?

> The constructor for new Sources in {{DataStreamSource}} does not set
