CDN Locks: A way to ensure data integrity in the CDN

on YouTube ↗27m

" summary

A simple API-backed lock object (username, CDN name, message, lock type, timestamp) is implemented in Traffic Portal/Traffic Ops and ships in ATC 6.0 to prevent concurrent snapshot/queue races. It supports soft/shared locks where many editors can change content but only the lock owner can snap/queue, and hard/exclusive locks that block others from editing or snapping. Admins can clear stuck locks, one lock per CDN is enforced, and demos show it working.
