Schema Definition

HelixQL uses a schema definition to define the structure of the graph. Note that every node, edge and vector has an implicit ID field. that is not in the schema definition.

​
Node Schema

Defines node types and their properties in the graph. 
N::NodeType {
  field1: String,
  field2: U32
}

​
Edge Schema

Defines relationships between nodes and their properties. 
E::EdgeType {
  From: String,
  To: String,
  Properties: {
    field1: String,
    field2: U32
  }
}

​
Vector Schema

Defines the vector type. 
V::VectorType {
  field1: String
}
