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

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.
