GRAPH.COPY

Usage: GRAPH.COPY <src> <dest>

The GRAPH.COPY command creates a copy of a graph, while the copy is performed the src graph is fully accessible.

Example:

Python

# Graphs list is empty
graph_list = db.list()

# Create Graph 'A'
graph_a = db.select_graph('A')
result = graph_a.query('CREATE (:Account {number: 516637})')

# Copy Graph 'A' to 'Z'
graph_z = graph_a.copy('Z')

# Graphs list including 'A' and 'Z'
graph_list = db.list()

# Query Graph 'Z'
result = graph_z.query('MATCH (a:Account) RETURN a.number')Query Graph 'Z'

Javascript

import { FalkorDB } from 'falkordb';

const client = await FalkorDB.connect();

// Create Graph 'A'
const graphA = client.selectGraph('A');
await graphA.query("CREATE (:Account {number: 516637})");

// Copy Graph 'A' to 'Z'
await client.copyGraph('A', 'Z');

// Query Graph 'Z'
const graphZ = client.selectGraph('Z');
const result = await graphZ.query("MATCH (a:Account) RETURN a.number");
console.log(result);

Rust

let client = FalkorDB::connect_default();
let graph_a = client.select_graph("A");

graph_a.query("CREATE (:Account {number: 516637})")?;
client.copy_graph("A", "Z")?;

let graph_z = client.select_graph("Z");
let result = graph_z.query("MATCH (a:Account) RETURN a.number")?;
println!("{:?}", result);

Java

FalkorDB client = new FalkorDB();

// Create Graph 'A'
Graph graphA = client.selectGraph("A");
graphA.query("CREATE (:Account {number: 516637})");

// Copy Graph 'A' to 'Z'
client.copyGraph("A", "Z");
Graph graphZ = client.selectGraph("Z");

// Query Graph 'Z'
ResultSet result = graphZ.query("MATCH (a:Account) RETURN a.number");
System.out.println(result);
