Throttling Requests by Single-Flighting
Blog post from Convex
The text discusses strategies for managing request flows in reactive applications to maintain responsive user interfaces and prevent resource wastage, focusing on the concept of "single flighting." Unlike throttling, debouncing, and rate limiting, single flighting ensures that only one request is processed at a time, adapting to server load and network speed, thereby providing natural back pressure. This technique is implemented in React using the Convex backend, featuring hooks like `useLatestValue` and `useSingleFlight` that optimize request handling without overwhelming the server. The article emphasizes the importance of balancing request frequency and system performance, while also considering scenarios like optimistic updates and the potential for missing intermediate data, particularly in applications that involve tracking changes over time.
