Indeed, using the same parallelism corrected the output. Thank you!

Hi!
The source runs parallel (n tasks), but the sink has a parallelism of 1.
The sink hence has to merge the parallel streams from the source, which
happens based on arrival speed of the streams, i.e., its not deterministic.
That's why you see the lines being mixed.
Try running source and sink wi
Hi all,
When I use out.collect() twice inside a faltMap, the output is sometimes
and randomly skewed. Take this example:
final StreamExecutionEnvironment env =
StreamExecutionEnvironment.createLocalEnvironment();
env.generateSequence(1, 10)
.flatMap((Long t, Collector out) -> {
