Review Comment:
   Using currentThread.interrupt() to signal a failed stream load may 
inadvertently impact the processing thread; consider using a more explicit 
cancellation mechanism (such as canceling the Future) to avoid unintended side 
effects.
   ```suggestion
                   future.cancel(true);
   ```
