Individual operators don't have their own maximum parallelism. If your sink is stateful then it will have a state descriptor somewhere and you can migrate its state. WebIf you restore from a savepoint that contains state for an operator that has been deleted, this will therefore fail. You can allow non restored state by setting the --allowNonRestoredState (short: -n) with the run command: {% highlight shell %} $ bin/flink run -s :savepointPath -n [:runArgs] {% endhighlight %}

This means that only partitions 1 and 2 will be consumed again by Flink, skipping partitions 3 and 4, which were previously mapped to sub task 2 (figure left).
