Review comment:
       Perhaps you can set both ` bounedness` and `Bouned `offset like this
   
   ```
   public KafkaSourceBuilder<OUT> setBounded(OffsetsInitializer stoppingOffsetsInitializer) {
           this.boundedness = Boundedness.BOUNDED;
           this.stoppingOffsetsInitializer = stoppingOffsetsInitializer;
           return this;
       }
   ```
   
   This allows to set `InstreamingMode `and `InbatchMode`
