Do I need prior experience with Postgres, Pinecone, or Neo4j?

No. The course names the three-service stack as the problem HelixDB solves, but you do not need prior experience with any one of them. You DO need to be comfortable in Rust — at the level of having written a small service with serde, tokio, and an HTTP client.

Is this just RAG with another vector database?

Partly. HelixDB carries vectors as a first-class primitive via V::Embedding and SearchV, so the vector half of RAG is identical. The difference is the graph half — ::In<EmbeddingOf> traversals climb from vector hits back to source documents inside the same query, with no second connection pool, no second schema, and no second transaction.

When is HelixDB the wrong choice?

Honest answer: anything that wants columnar OLAP execution semantics — Spark, DuckDB, or a multi-tenant analytical warehouse. HelixDB is built for graph-shaped and vector-shaped workloads in one process. Module 1 names the boundary explicitly so you can rule it in or out for your stack before you commit.

When will I have access to the lectures and assignments?

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

What will I get if I subscribe to this Specialization?

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

Stop stitching three databases together. HelixDB is a Rust-native graph plus vector engine that holds your nodes, your embeddings, your typed edges, and your key-value documents in one process — no separate Postgres, no separate Qdrant, no separate Neo4j. This course walks a Rust-fluent engineer from helix init through a typed HelixQL schema, the helix check and helix compile pre-deploy gates, side-by-side graph traversal and vector search in the same query language, and a typed Rust client that calls a live HelixDB instance with four runtime contracts. Every primitive you meet is wired into a working .hx schema and a running engine you can install in one command. Module 4 puts graph traversal verbs (Out, In, WHERE, ORDER, RANGE) and vector top-k search side by side in the same query language, and adds ShortestPathDijkstras with composable weight expressions for cost-aware routing. You finish with the canonical hybrid-RAG pattern — SearchV returns top-k embeddings, then a typed edge climbs back to the source documents — shipped as a typed Rust client (helix-rs plus serde) with four runtime assertion contracts. The course closes with an honest read on where HelixDB is the wrong choice: columnar OLAP, Spark execution semantics, multi-tenant analytical warehouses.

Détails du module

The unified-engine pitch — why one process holding graph + vector + KV + document beats stitching Postgres, Qdrant, and Neo4j at the application layer. You will see the four-layer Helix stack and the honest boundary where HelixDB is the wrong choice.

The three-element schema in HelixQL and the four-keyword QUERY shape. Walks N::, V::, E:: declarations, INDEX + UNIQUE INDEX, field types, default values, and a queries.hx file end to end.

The helix-cli pipeline walked verb by verb. helix init scaffolds the project; helix check is the lint pass; helix compile is the type-safe lower-to-Rust artifact; helix push dev deploys to a local instance on port 6969 where every QUERY becomes an HTTP endpoint.
