01 |LIVE QUERIES
Subscribe to changes. The database is the event system.
Subscribe to a table
Every change to the matching records streams to the client as it commits.
How LIVE SELECT works-- Subscribe to all changes on messages in a chat room
LIVE SELECT * FROM message WHERE room = room:general;
Subscribe to a record
One record's changes, pushed as they happen, with no polling in between.
-- Subscribe to changes on a specific record
LIVE SELECT * FROM user:jaime;
02 |EVENTS AND TRIGGERS
Reactive workflows inside the database. Events fire on change, in the engine.
Table events
SurrealQL on CREATE, UPDATE or DELETE: audit trails, notifications, cascading logic.
Field-level triggers
React to a change on one field: derived values, business rules, side effects.
WebSocket streaming
Clients connect over WebSocket and the database streams to them directly.
Collaborative patterns
Shared editors, multiplayer games and live dashboards, every change pushed as it commits.
How live queries work
A LIVE SELECT is a persistent subscription. SurrealDB watches the matching data and pushes each create, update or delete over WebSocket.
The database is the event source
Live queries and events cover many of the cases a broker such as Kafka or RabbitMQ is added for.
03 |REAL-TIME AGENTS
Coordination for multi-agent systems. One commit, pushed to every agent.
Handoffs as commits
When one agent commits a finding, a live query pushes it to every other agent watching the same records.
Shared context
Agents read and write one knowledge graph, so context updates arrive as data changes, not as messages.
ACID across agents
Concurrent writes from many agents commit in order, with no lost updates and no reconciliation step.
THE PLATFORM
Everything an application and its agents know. Five surfaces, one engine.
Database
Document, graph, vector, time-series and relational in one engine.
Agent Memory
What an agent learns, with its source and its time, in the same engine.
Cloud
Managed clusters in the regions you choose, scaled on demand.
Studio
Query, explore and design the schema from the browser.
MCP
Every model that speaks MCP reaches the database and the memory directly.
IN PRODUCTION
Trusted at scale. Samsung, Nvidia, Verizon, Tencent, and Walmart run on SurrealDB.

FROM THE TEAMS
SurrealDB gives us a foundation where we can unify semantic search, knowledge graphs, and AI-driven decision making without stitching together multiple systems. Collapsing responsibility into SurrealDB has become our default engineering posture.
