Roblox Server & Shared Data

When to Load

Load for leaderboards, messaging, MemoryStore coordination, world state, seasons, or guilds. Player persistence: roblox-data; Open Cloud: roblox-cloud.

Quick Reference

OrderedDataStore (Leaderboards)

• Sortable DataStore: string keys (tostring(UserId)), integer sort values; GetSortedAsync → pages; BatchGetAsync multi-key read (missing keys omitted).
• Budget bursts via GetRequestBudgetForRequestType(OrderedWrite) (per server: 30 + numPlayers×5 writes/min).
• Leaderboards only, never player saves. Keep player_<UserId> a static key substring so RTBF templates match.

MessagingService (Cross-Server)

• SubscribeAsync / PublishAsync; no delivery or ordering guarantee — design for idempotency.
• Request/response: {reqId} correlation + ack + timeout; no ack ≠ not executed — replay same reqId, don't double-grant.
• Budget broadcast receives, not just sends; limits and polling trade-offs: full.md.
