Optimizing Database Queries for High Traffic
A single N+1 query can crash an app during a flash sale. I audited our entire Eloquent layer to ensure every query was lean and indexed.
- N+1 Auditing: I used the 'Bullet' library during development to catch and eliminate unoptimized relationship loading.
- Composite Indexing: I implemented indexes on
(shop_id, created_at)to make our analytics dashboards load in under 200ms. - Query Profiling: I used
EXPLAIN ANALYZEto identify full table scans and replaced them with efficient index seeks.
