Reflex state synchronization limits for high-frequency updates

State Synchronization Behavior

Reflex maintains application state on the server and synchronizes changes to the frontend using WebSockets. This architecture utilizes a delta update mechanism to transmit only modified state variables to the client, reducing overall network traffic.

Concurrency and Performance Constraints

In scenarios involving high-frequency state updates or large state objects, the reliance on a centralized server-side state may introduce bottlenecks. Specifically, the per-session memory overhead on the backend and the potential for WebSocket congestion during rapid event triggers raise concerns regarding scalability and UI responsiveness.

There is uncertainty regarding how the framework handles race conditions when multiple concurrent event handlers attempt to modify the same state variable within a single session.

• What are the documented limits for the frequency of state updates before WebSocket latency impacts the user experience?
• How does Reflex resolve conflicting state modifications triggered by concurrent event handlers?
