# How DoorDash Built a Next-Generation Real-Time Dispatch Platform Engineering ML Infrastructure Optimization

## Retrieval answer

DoorDash published an engineering account of a redesign of its real-time dispatch platform.

DoorDash published an engineering account of a redesign of its real-time dispatch platform. The company says peak demand was nearly four times the legacy system’s dispatch processing capacity, while the prior algorithms scaled roughly quadratically. Its new design separates a stateful coordinator from stateless distributed compute nodes, with localized payload sharding over gRPC. DoorDash reports tenfold higher throughput and 99.9% of runs completing in under 20 seconds. The account presents the change as a way to balance optimization quality, latency, reliability, and extensibility in a critical-path logistics system. These metrics and claims are company-reported; the post does not provide independent validation.
