Is MySQL Still Good Enough for Scaling Startups?

On July 1st, a question popped up in the KPH Mafia group:

"MySQL okke mathiyo .. this much data handling nu?"

Roughly translated: "Can MySQL really handle this level of data?"

A classic dilemma for any growing startup.

When MySQL works just fine: Basic CRUD-heavy apps

Dashboards with moderate data

Up to ~100K users with optimization

Caching and indexing in place

When you may outgrow it: Millions of rows added daily

Real-time analytics and dashboards

Complex JOINs and nested queries choke speed

Need for horizontal scaling

Popular alternatives: PostgreSQL – Modern + relational

MongoDB / Firestore – NoSQL & flexible

ClickHouse / BigQuery – Heavy analytics

Lesson: Use MySQL when you start scale only when you hit its ceiling. Tools should follow the problem, not the hype
