⚡ [Performance] Optimize N+1 DB Queries in harvest.py#20
Conversation
Refactors the `promote_l1`, `promote_l2`, and L3 auto-draft loops in `scripts/harvest.py` to collect parameters and perform batched database updates using `conn.executemany` followed by a single commit outside the loop. A benchmark measured a 10x performance improvement (~91% execution time reduction) for 500 records. Co-authored-by: masuda-so <258961222+masuda-so@users.noreply.github.com>

💡 What: Replaced the N+1
executeandcommitoperations inside the L1/L2 promotion and L3 auto-draft loops inscripts/harvest.pywithexecutemanyand a singlecommitoutside the loop.🎯 Why: Executing and committing individual database queries inside a loop creates significant overhead in SQLite. Batching updates mitigates this CPU and I/O inefficiency, leading to substantially faster loop execution.
📊 Measured Improvement: A test case benchmarking 500 records was written. The baseline N+1 queries took ~2.1886 seconds. The optimized version took ~0.1919 seconds, reducing execution time by over 10x (~91%).
