Can I yield AssetMaterializations or simiilar directly from a Sensor context or do I need to execute an Op? E.g. I also could start a in process job inside the sensor just for logging the Assets but it seems a big odd. Just need it to translate/map pub-sub/kafka events to AssetEvents and starting a pod for that seems overkill.

Unfortunately this is not possible right now from a sensor / schedule evaluation function. Added an issue to track
