有这样的密码sql:
match p=(:Devices{name:"123.123.123.123"})-[r:Cost*..6]->(:Devices{name:"123.123.123.124"}) with p return p;
然后返回:
{u'p': (123.123.123.123)-[:Cost {Cost: 21}]->(123.123.123.120)-[:Cost {Cost: 92}]->(123.123.123.110)-[:Cost {Cost: 82}]->(123.123.123.119)-[:Cost {Cost: 91}]->(123.123.123.123)-[:Cost {Cost: 56}]->(123.123.123.130)-[:Cost {Cost: 24}]->(123.123.123.124)}
我的路径上有环,以及如何避免这种情况。
最后为什么我的查询如此求索和查询 在10深度以下的路径将花费大约1000s-2500s。
有我的配置:
dbms.memory.heap.initial_size=4096m
dbms.memory.heap.max_size=9192m
dbms.memory.pagecache.size=10g
dbms.threads.worker_count=16
答案 0 :(得分:0)
也许您打算指定1到6个跃点之间的路径,而不是确切地指定6个跃点:
match p=(:Devices{name:"123.123.123.123"})-[r:Cost*1..6]->
(:Devices{name:"123.123.123.124"}) with p return p;
