Under the hood
How a flag change reaches every user
You save a change
A flag update is written to the origin control plane and versioned immediately.
Origin fans out
A streaming diff is broadcast to every edge PoP simultaneously over persistent connections.
Edge applies locally
Each node patches its in-memory rule set. No full sync — just the delta.
User gets it instantly
The next SDK evaluation reads the new rule locally. Zero added latency to your request.
