Case Study: Cash App scales to 400TiB and 4 million QPS with PlanetScale

Cash App scales to 400TiB and 4 million QPS with PlanetScale

Cash App, the popular finance application, faced significant scaling and operational challenges with its self-hosted Vitess database clusters. Managing hundreds of shards internally led to high complexity, a heavy maintenance burden, and scaling limitations as data volumes grew. This prompted their search for a managed solution, leading them to partner with PlanetScale and its fully-managed database platform.

PlanetScale implemented a seamless migration of Cash App's massive database infrastructure to its cloud service. The solution provided deep Vitess and AWS expertise, ensured regulatory compliance, and delivered a stable, scalable platform. As a result, Cash App now reliably handles peaks of 4 million queries per second across 400TiB of data, cut p99 latency by 50%, and significantly reduced operational overhead, freeing engineers to focus on core product development.
