SurrealDB 3.0 turns the database into the agent's memory - multi-model, ACID, and queryable in a single round trip. [Explore Agent Memory, our agent memory layer](https://surrealdb.com/agent-memory) 03 |WHAT'S NEW ## Dive into SurrealDB 3.0 Native WASM extensions, first-class file storage, an indexing overhaul, client-side transactions, computed fields, a stable GraphQL interface, and 150+ closed bugs - drawn from a year of alpha and beta releases. [See all 3.0 features](https://surrealdb.com/surrealdb/features) [Read the full release notes](https://surrealdb.com/releases) ### Streaming query planner A new execution engine streams results as they're produced, batches scanner retrievals, and unlocks concurrent writes on HNSW vector indexes. Workloads finish faster and stay predictable as data grows. QUERY PLAN scan idx_users 0.4 ms batch fetch orders 0.9 ms vector kNN (HNSW) 1.3 ms stream → client 1.7 ms ### WebAssembly extensions Run WASM plugins directly inside SurrealQL. Embed AI logic, business rules, and custom transforms next to your data, with first-class access to the engine's primitives. DEFINE MODULE ai FROM bucket:wasm mod::ai::rerank Loaded mod::nlp::tokenise Loaded mod::ai::classify Loading ### File storage Buckets and file pointers are first-class types in SurrealQL. Store, fetch, and stream files alongside structured data inside one transaction boundary - no separate object store glue. BUCKET assets BACKEND s3 report.pdf 2.4 MB model.bin 164 MB image.png 890 KB data.csv 12 KB ### In-memory engine A lock-free, MVCC-based engine that delivers ultra-low latency with full ACID guarantees and massive concurrency. Optional background persistence keeps durability on the table without compromising throughput. P99 LATENCY · 1M ROWS disk 1.20 ms memory 0.08 ms ACID Yes Concurrent MVCC Persist Optional ### Indexing overhaul Concurrent index updates under heavy write load, range scans on compound indexes, early-stop iteration on START/LIMIT, and a new ALTER INDEX statement for safe decommissioning. INDEX PLANNER idx_users_email HIT idx_orders_ts RANGE idx_legacy_v1 REMOVING Concurrent Yes ALTER INDEX Safe ### Client-side transactions Group operations across multiple SDK calls and commit when ready. Full ACID guarantees, no server-side state hacks, no half-applied writes. TX 0x9a3f · CLIENT BEGIN ✓ INSERT user:01 ✓ INSERT order:42 ✓ UPDATE balance ✓ COMMIT Ready ### Custom API endpoints DEFINE API ships HTTP routes and middleware directly inside SurrealQL, complete with a permissions model. Pull external middleware out of your architecture without losing control. METHOD PATH STATUS GET /users 200 POST /orders 201 PATCH /users/:id 200 DELETE /sessions/:id 204 ### Record references Bidirectional links at the schema level. Cleaner queries, faster graph traversal, and no manual relation bookkeeping - the database keeps both sides in sync for you. person:billy REFERENCED BY name "Billy" licenses <~license COMPUTED REF license:42 SCHEMA owner person:billy REFERENCE valid true ### Computed fields Define logic once in the schema with the new COMPUTED keyword, evaluated consistently at query time. Replaces the futures type with shorter syntax, guardrails, and no per-record overhead. DEFINE FIELD valid ON license COMPUTED expires > time::now() SELECT id, valid license:01 true license:02 false license:03 true ### GraphQL is stable A re-architected GraphQL interface with full mutation support, built-in authentication, permission enforcement, rich filtering, and N+1 query optimisations. Enabled by default - no experimental flag. POST /graphql 200 OK query users(limit: 5) { id, name, posts { title } } Stable Auth N+1 ✓ ### Production-ready foundations Synced writes are now the default for durability. Over 150 bugs closed, automated CRUD benchmarks on every PR, and the Go and Java SDKs at 1.0 - the safer defaults are now the standard. PRODUCTION READY Bugs fixed 150+ Synced writes Default Go SDK 1.0 Java SDK 1.0 04 |TALK TO US ## See SurrealDB 3.0 in your stack Book a personalised walk-through with our team.
