Three-tier memory hierarchy.
Hot content lives in RAM. Warm content drops to NVMe. Cold content drains to S3-compatible object storage. Promotion and demotion happen per-request, in microseconds.
- L1 RAM · 0.4ms
- L2 NVMe · 1.2ms
- L3 Object · 8ms

Built from the protocol up.
Tag-based purge.
Magento ships every block with surrogate-keys. Velocity invalidates by tag — not by URL pattern.
Edge-side includes.
Cache the page, render the cart at the edge. Native ESI parsing, no shim.
Observability.
OpenTelemetry traces and Prometheus metrics out of the box. Plug into Prism or your own stack.
Build the cache. See the cache.
Both products run on commodity hardware, ship with full source under a per-node licence, and integrate with your existing observability stack.
