Scaling MySQL Database with ProxySQL

A large SEO enterprise platform experienced rapid growth in traffic and required a database solution that could handle heavy load, provide high availability, and support horizontal scaling. Their backend infrastructure relied heavily on MySQL as the primary database, but the number of concurrent connections and the volume of database queries increased to the point where their single MySQL instance became a bottleneck.

The engineering team faced several challenges:

• Database connection management: The system was struggling with managing a large number of simultaneous connections from the web servers, leading to performance degradation.
• Failover and high availability: The platform required high availability in case of database failures, but handling failovers manually was too slow.
• Scalability: Horizontal scaling (adding more database replicas) needed to be managed efficiently to prevent overloading a single MySQL instance.

To address these challenges, the team decided to implement ProxySQL as a SQL proxy layer between their applications and MySQL database clusters
