Please describe.**\nI have a `PushSource` which I used at offline time to push features that I created during training (for example, embedding of entity after model training),\n\nThe problem is that `PushSource` **requires** me to provide a `batch_source` but I dont have this kind of features before training (Because this features are generated only after training) so I must do this overhead/workaround:\n* Create a dummy parquet file to store at least one value (else if I remember right I got an error)\n* Create a FileSource  to point the parquet file.\n* Point the `batch_source`  to the `FileSource`\nAll of this need to done for each feature view of a push source that I want,\n\n**Describe the solution you'd like**\nExpected behavour will be to leave the `batch_source` empty and only create `FV` and `PushSource`\n\n**Additional context**\nYou can see example of the workaround [here](https://github.com/RHEcosystemAppEng/rec-sys-app/blob/main/feature_repo/data_sources.py#L52)\n","author":{"url":"https://github.com/itay1551","@type":"Person","name":"itay1551"},"datePublished":"2025-06-10T10:46:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/5440/feast/issues/5440"}
