Canva Scales Session Revocation to 100M Users with S3‑Backed Revocation Lists
Canva replaced its MySQL‑driven revocation cache with durable Amazon S3 revocation lists, letting it seed in‑memory caches for over 100 million active sessions without a deployment‑time database stampede. The S3‑backed approach cuts DB lookups, shrinks cache size, and keeps session revocations fast and reliable at massive scale.
