Getting 10 Million Downloads Fast (Without Breaking Your App)

Devsisters, a Korea-based game developer, has seen significant success with its mobile game Cookie Run: Kingdom, which has garnered over ten million downloads and handles hundreds of thousands of concurrent users. The game's architecture was designed for scalability from the beginning, using CockroachDB as its database solution. This decision allowed Devsisters to easily scale up their database to accommodate the unexpectedly high workload generated by the game's success. Had they chosen a different database, scaling would have been more difficult and potentially hindered the game's growth.
