Multi-Tier Caching Strategies for Data-Heavy APIs

Retrieving data from a relational database is slow. We employ a rigorous multi-tier caching strategy using CDN points, Redis clusters, and in-memory application caches.

Cache Invalidation is Hard

We use precise tagging to invalidate distributed caches within milliseconds of a core database write, ensuring that API consumers always receive the absolute latest valuation metrics without sacrificing high-speed response times.
