Currently, only the SQLite online store supports versioned reads/writes. All other online stores raise `VersionedOnlineReadNotSupported` when a versioned ref is used.\n\nThe implementation pattern (see `sqlite.py` for reference) involves:\n1. **Write path**: When `enable_online_feature_view_versioning` is enabled, materialize data into a version-specific table/key namespace (e.g., `{project}_{fv_name}_v{version}`)\n2. **Read path**: Route version-qualified lookups to the correct versioned table/key namespace\n\n## Reference implementation\n\n- SQLite online store: `sdk/python/feast/infra/online_stores/sqlite.py`\n- Store file: `sdk/python/feast/infra/online_stores/dynamodb.py`\n\n## Related\n\nPart of #2728","author":{"url":"https://github.com/franciscojavierarceo","@type":"Person","name":"franciscojavierarceo"},"datePublished":"2026-03-26T18:52:47.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/6163/feast/issues/6163"}
