In the code [here](https://github.com/feast-dev/feast/blob/27ec8ec26b2884d09df3ee3e648b96824e1f2b4c/sdk/python/feast/utils.py#L505)\n, if an ODFV has the `write_to_online_store` flag set, it is treated as a regular feature view. As a result, it gets queried from the offline store.\n\nHowever, ODFVs are not historical feature views and do not have any data in offline stores, so they should never be queried there.\n\n## Steps to reproduce\nRun `get_historical_features` for an ODFV with `write_to_online_store=True`.\n\n### Specifications\n\n- Version: 0.57.0\n- Clickhouse offline store.\n\n## Possible Solution\nNot sure yet, but basically remove the condition? Is it even needed here? Seems incorrect...","author":{"url":"https://github.com/astronautas","@type":"Person","name":"astronautas"},"datePublished":"2025-12-15T09:07:17.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/5776/feast/issues/5776"}
