Reflex WebSocket State Delta Batching Limit
Reflex synchronizes frontend UI state with a backend Python State class through a persistent websocket connection managed by FastAPI and Next.js. Event handlers modify backend state, triggering delta serialization and transmission to the browser, where updates trigger reactive re-renders. The framework currently lacks a built-in configuration point to limit
