Case Study: Kami scales to 30M users with CockroachDB from Cockroach Labs

How Kami migrated their mission-critical workload from Postgres to CockroachDB in 4 months

Kami, the world’s #1 digital classroom application, needed to scale fast during the pandemic as usage surged by more than 1M users per week. Their Postgres database couldn’t keep up with the write-heavy workload and rapid growth, creating urgent scaling and performance challenges.

Cockroach Labs helped Kami migrate its mission-critical workload from Postgres to CockroachDB, a distributed SQL database, in about four months. Using a live migration with mirrored writes and read validation, Kami gained the horizontal scalability and resilience it needed, ultimately supporting over 30 million users across 180+ countries and driving 20x business growth.
