图引擎

具有内置算法的邻接表存储，用于图遍历和分析。

用法

import barabadb/graph/engine

var g = newGraph()
let alice = g.addNode("Person", {"Name": "Alice"}.toTable)
let bob = g.addNode("Person", {"Name": "Bob"}.toTable)
discard g.addEdge(alice, bob, "knows")

let bfs = g.bfs(alice)
let path = g.shortestPath(alice, bob)
let ranks = g.pageRank()

算法

算法	描述
bfs	广度优先遍历
dfs	深度优先遍历
dijkstra	最短加权路径
pageRank	节点重要性排名
louvain	社区检测
patternMatch	子图同构

Cypher 查询

import barabadb/graph/cypher

var engine = newCypherEngine(g)
let results = engine.execute("""
  MATCH (p:Person)-[:KNOWS]->(friend:Person)
  WHERE p.name = 'Alice'
  RETURN friend.name
""")
