  Start = {person};
  Result = SELECT t
           FROM Start:s -(KNOWS:e)-> Person:t;
  PRINT Result;
}

Graph Schema

Vertex Types

• Define entities in the graph
• Have properties (attributes)
• Can have primary keys
• Support custom data types

Edge Types

• Define relationships between vertices
• Support directional connections
• Have properties
• Can be undirected

Properties

• Store data on vertices/edges
• Multiple data types supported
• Can be indexed
• Support default values

REST++ APIs

• HTTP-based interface
• JSON request/response format
• RESTful endpoint design
• Real-time data loading
• Query execution

GSQL Query Patterns

Basic Query Structure

CREATE QUERY queryName(PARAMETERS) FOR GRAPH graphName {
  // Variable declarations
  // Pattern matching
  // Aggregations
  // Output
}

Vertex Pattern Matching

Query Single Vertex Type

Start = {Person.*};
Result = SELECT * FROM Start;

Query Multiple Vertex Types

Start = {Person.* UNION Company.*};
Result = SELECT * FROM Start;

Traversal Patterns

Single-Hop Traversal

Result = SELECT t
         FROM Start:s -(KNOWS:e)-> Person:t;

Multi-Hop Traversal

Result = SELECT t
         FROM Start:s -(KNOWS:e)-> Person:t -(WORKS_AT:e2)-> Company:c;

Variable-Length Traversal

Result = SELECT t
         FROM Start:s -(KNOWS:e)->* Person:t;

Aggregation Patterns

Count Aggregation

Result = SELECT COUNT(DISTINCT t)
         FROM Start:s -(KNOWS:e)-> Person:t;

Property Aggregation

Result = SELECT s.name, COUNT(DISTINCT t)
         FROM Start:s -(KNOWS:e)-> Person:t
         GROUP BY s.name;

Filtering Patterns

Where Clause

Result = SELECT *
         FROM Start
         WHERE age > 25 AND status == "active";

Having Clause

Result = SELECT s.name, COUNT(DISTINCT t) as cnt
         FROM Start:s -(KNOWS:e)-> Person:t
         GROUP BY s.name
         HAVING cnt > 5;

Data Loading Operations

Insert Vertices

{
  "vertices": {
    "Person": {
      "alice": {
        "name": "Alice",
        "age": 30,
        "email": "[email protected]"
      },
      "bob": {
        "name": "Bob",
        "age": 25,
        "email": "[email protected]"
      }
    }
  }
}

Insert Edges

{
  "edges": {
    "Person": {
      "alice": {
        "KNOWS": {
          "Person": {
            "bob": {
              "since": "2020-01-15"
            }
          }
        }
      }
    }
  }
}

Batch Loading

connector.load_from_csv(
    file_path="data.csv",
    vertex_type="Person",
    mapping={"name": "Name", "age": "Age"}
)

Graph Algorithms

Built-In Algorithms

PageRank

RUN QUERY pagerank(max_iterations=100, damping_factor=0.85)

Measures vertex importance in the graph.

Shortest Path

RUN QUERY shortest_path(source_vertex, target_vertex)

Finds shortest path between two vertices.

    query_name="getNeighbors",
    parameters={"person": "Alice"}
)

Query with Timeout

result = connector.run_query(
    query_name="complexQuery",
    parameters={...},
    timeout=60
)

Batch Query Execution

results = connector.batch_query(
    queries=[
        {"name": "query1", "params": {...}},
        {"name": "query2", "params": {...}}
    ]
)
