Note that projected results are immutable `Row` objects, so use `db.query(Model).filter(...).update()` for atomic modifications. -## 2026-02-07 - Transaction Consolidation for Performance -**Learning:** Performing multiple `db.commit()` calls in a single endpoint handler increases latency due to multiple round-trips and disk I/O. Using `db.flush()` allows intermediate results (like atomic increments) to be available for queries in the same transaction without the cost of a full commit. -**Action:** Consolidate multiple database updates into a single transaction. Use `db.flush()` when you need to query the database for values updated via `update()` before the final commit. - -## 2026-02-08 - Return Type Consistency in Utilities -**Learning:** Inconsistent return types in shared utility functions (like `process_uploaded_image`) can cause runtime crashes across multiple modules, especially when some expect tuples and others expect single values. This can lead to deployment failures that are hard to debug without full integration logs. -**Action:** Always maintain strict return type consistency for core utilities. Use type hints and verify all call sites when changing a function's signature. Ensure that performance-oriented optimizations (like returning multiple processed formats) are applied uniformly. +## 2026-02-06 - Spatial Query Optimization +**Learning:** For small distances (e.g., < 1km), the Haversine formula is computationally expensive due to multiple trigonometric calls. An equirectangular approximation (Euclidean distance on scaled lat/lon) is ~4x faster and sufficiently accurate for pre-filtering. +**Action:** Use `equirectangular_distance_squared` as a fast pre-filter to identify candidates within radius, then compute accurate Haversine distance only for those candidates. Always handle longitude wrapping at the International Date Line.
