⚡ Bolt: Optimize LendingService aggregation pipelines#34
Conversation
This commit replaces N+1 query patterns in `get_active_lendings` and `get_recent_consumable_usage` with single MongoDB aggregation pipelines. Key improvements: - `get_active_lendings`: Replaced 2N+1 query loop with a single `$lookup` pipeline. - `get_recent_consumable_usage`: Moved sorting and limiting to the database layer to avoid fetching all records into memory, and replaced N+1 loop with joins. Expected impact: - Significant reduction in database roundtrips and network latency. - Lower memory consumption for usage history reporting. - Improved response times for active lending and recent activity views.
