Roblox DataStores

Persist data across sessions in Roblox with DataStoreService: loading on join, saving on leave and shutdown, safe updates, retries, and ordered stores for leaderboards. Server-side only.

When to use

• Use to save/load player progress (coins, inventory, levels), build persistent leaderboards, or fix data loss, overwrites, and throttling.
• Use when server code calls DataStoreService, GetDataStore, GetAsync, SetAsync, UpdateAsync, or GetOrderedDataStore.

When not to use: general scripting, services, remotes, the client/server split → roblox-luau. High-frequency temporary state (matchmaking, per-round) → memory stores (a different service). Engine-agnostic persistence theory → save-systems.
