Photon Realtime Cache Write Ordering Boundary

Server Authority Governs Cache Writes

Confirmed Fact

The server maintains the authoritative global room cache. Concurrent RaiseEvent calls from multiple clients do not mutate the cache directly; they trigger server-side processing that dictates the write order.

Likely Explanation

Photon Realtime guarantees ordering through its internal server logic, not by enforcing a single master client. The server serializes or orders these events based on its internal processing pipeline (e.g., arrival time or application logic), ensuring a consistent state for all connected clients.

Steps for Verification

1. Examine the specific Photon Realtime server implementation documentation for event serialization guarantees.
2. Test concurrent RaiseEvent calls from several clients and verify the resulting cache state sequence against expected ordering.

Missing Diagnostic Detail

To refine the answer, is the specific Photon Realtime server implementation running a custom event handler or relying solely on the default framework behavior?
