How Dragon Quest Walk handled millions of players using Cloud Spanner
summary
Colopl runs Dragon Quest Walk on Cloud Spanner, handling over 5 million downloads in the first week and millions of monthly active users with thousands of queries/sec across hundreds of Spanner nodes. Engineering work includes a Laravel Spanner driver on GitHub, schema interleaving to avoid cross-node joins, presplit warm-up of splits before launch, and careful scale-in throttling to avoid 30s stalls; launch succeeds with zero Spanner-caused outages and claimed TCO savings versus other clouds and on‑prem.
