Your database is slow. Here's why (and how to fix it):

1/ Most apps handle 10K users easily. But at 1M users? Everything breaks.

The problem isn't your code. It's how your database processes millions of queries per second.

2/ Indexing Mistake #1: Adding indexes everywhere

Each index speeds up reads but slows down writes. You need strategic, composite indexes on your hottest query paths.

Example: Index on (user_id, created_at DESC) beats separate indexes every time.

3/ The N+1 Query Killer

Your ORM is secretly making 1000 database calls instead of 1.

One query to fetch users → 1000 queries to fetch their posts

Solution: Eager loading & JOINs. Always.

4/ Caching Layer = 10x Performance

95%+ cache hit rate can reduce database load by 10x.

But cache invalidation? That's the hard part.

Time-based expiration vs event-based invalidation—choose based on consistency needs.

5/ Connection Pools: Size Matters

Too few → bottlenecks Too many → CPU thrashing

Formula: (core_count × 2) + disk_spindles

But always load test for YOUR workload.

6/ When to Shard

Last resort. Only after you've: ✅ Optimized queries ✅ Added caching ✅ Implemented read replicas ✅ Maxed out vertical scaling

Sharding adds massive complexity. Make sure you need it.

7/ We wrote a complete guide covering all of this (+ execution plans, materialized views, monitoring strategies)

1000 words of actionable techniques.
