Scalability and Performance

Scalability and Performance

Overview

Design for reasonable performance; optimize hotspots with data.

Concepts

• Caching (HTTP, Redis)
• Database indexing and query optimization
• Async jobs and queues
• Horizontal vs vertical scaling

Example

• Cache GET /api/projects in memory for 60s to reduce DB load

Checklist

• Measure first (profiling, APM)
• Add indexes for slow queries
• Avoid N+1 queries
