Sharding high-throughput Redis without downtime
Read about how we rolled our new sharded infrastructure out to production without a millisecond of downtime and how it improved Inngest's overall performance.
**Every day, more and more software teams rely on Inngest for their core infrastructure which results in increased load on our core systems. When building distributed systems, vertical scaling can only get you so far. Because of that, we took on a project to horizontally scale by sharding our most crucial database, which serves more than 50,000 requests per second at low latency. As Inngest is critical infrastructure for many customers, we aim to avoid maintenance windows at all costs. In this post we’ll walk through how we sharded our function state database with zero downtime.**
