⚡️ Speed up method BaseArangoService.get_record_by_path by 219%

[codeflash-ai]

📄 219% (2.19x) speedup for BaseArangoService.get_record_by_path in backend/python/app/connectors/services/base_arango_service.py

⏱️ Runtime : 18.8 milliseconds → 5.89 milliseconds (best of 136 runs)

📝 Explanation and details

Optimizations made:

• Imported NODE_COLLECTIONS, EDGE_COLLECTIONS at the module level for reuse.
• Combined the query string building to avoid multi-line f-string overhead and to make it more cache-friendly.
• Moved all string formatting for logger messages outside the logging call to prevent repeated formatting cost if logger level is above message's level.
• Used db.aql.execute(..., batch_size=1) to limit records pulled from DB.
• Used a single direct for-loop over the cursor, which exits immediately on the first hit, thus reducing overhead versus next(cursor, None). This is efficient, as only the first matching record is required.
• Preserved exactly all logger messages, code style, and function signatures as per the requirements.
• No behavioral changes; maintains identical exception, logging, and return patterns.
