What are HelixDB’s key features?

HelixDB provides:
  • High Performance: Purpose-built storage engine optimized for both graph and vector operations
  • Type Safety: Explicit type definitions to ensure data integrity
  • Developer-Friendly: Simple setup and migration
  • Secure: Options for encryption at rest

​
How does HelixDB store data?

HelixDB uses a property graph model with three core components:
  • Nodes: Represent entities with unique identifiers and properties 
    N::NodeType {
  field1: String,
  field2: U32
}
  • Vectors: Represent entities with unique identifiers and vector embeddings 
    V::VectorType {
  field1: String,
  field2: U32
}
  • Edges: Represent relationships between nodes and/or vectors, with directionality and properties 
    E::EdgeType {
  From: String,
  To: String,
  Properties: {
    field1: String,
    field2: U32
  }
}
This model allows for rich representation of complex domains while maintaining query performance.
