def shutdown(): Future[Done]

Override shutdown to define your own shutdown process or wait for the sink to finish.
Override shutdown to define your own shutdown process or wait for the sink to finish. The default shutdown makes the following assumptions:
- The stream materializes to a Future or a Product (Tuple, List, etc.) for which the last element is a Future
- This Future represents the state whether the stream is done
- The stream has the killSwitch as the first processing stage In which case you do not need to override this default shutdown if there are no further shutdown requirements. In case you override shutdown, it is recommended that super.shutdown() be called on overrides even if the stream only partially meets the requirements above.
returns
A Future[Done] that gets completed when the whole stream is done.
