Day 26: Building Production-Ready Metrics APIs
Week 4: Metrics Collection System
What We're Building Today
Today we're creating the API layer that transforms raw metrics data into actionable insights. Think of it as building the query engine that powers dashboards like Grafana or DataDog - where engineers can slice, dice, and export their metrics data efficiently.
Today's Agenda:
Query endpoints with flexible filtering
Time-series data aggregation APIs
Export functionality for reports
Redis-powered caching layer
Performance optimization strategies
Why This Matters in Real Systems
When Netflix monitors video streaming quality or Uber tracks ride completion rates, they're not just storing metrics - they're querying millions of data points in real-time. The API layer we're building today is what makes those lightning-fast dashboards possible.
