CF-Incidents Cache - Regionalized Generic Tiered Cache for higher hit ratios

[ENF News Bot]

You can now achieve higher cache hit ratios with Generic Global Tiered Cache. Regional content hashing routes content consistently to the same upper-tier data centers, eliminating redundant caching and reducing origin load.

How it works​

https://developers.cloudflare.com/changelog/rss/#how-it-works

Regional content hashing groups data centers by region and uses consistent hashing to route content to designated upper-tier caches:

• Same content always routes to the same upper-tier data center within a region.
• Eliminates redundant copies across multiple upper-tier caches.
• Increases the likelihood of cache HITs for the same content.

Example​

A popular image requested from multiple edge locations in a region:

• Before: Cached at 3-4 different upper-tier data centers
• After: Cached at 1 designated upper-tier data center
• Result: 3-4x fewer cache MISSes, reducing origin load and improving performance
