提高Neo4j密码查询性能

时间：2019-02-12 10:17:06

标签： performance neo4j cypher

嗨，我正在运行一个密码查询，该查询将节点追加到图形上，密码很大，这影响了性能，当前查询需要3780毫秒，我可以做些什么使它更快？
（由于大小限制，我无法放置整个查询）

我有一个约束：

CREATE CONSTRAINT ON (country:country) ASSERT country._id IS UNIQUE

1 个答案:

答案 0 :(得分：0)

我只是接受您查询的第一行：

MERGE (pisrael:country {_id:'israel'})
MERGE (pisrael)-[:Has]->(pyafo:city {_id:'yafo'})

您说您只对:country(_id)施加了限制

因此对于第一行来说，它是完美的，它将很快！

但是MERGE (pisrael)-[:Has]->(pyafo:city {_id:'yafo'})可能会很慢...

为什么？

您要数据库查找节点(:city {_id:'yafo'})，然后创建关系（如果不存在）。 但是，如果您有10亿个city节点怎么办？ ...这部分会很慢，因为Neo4j将必须对city节点进行完整扫描。 为了避免这种情况，您应该创建索引或约束。

您可以在其余查询中应用此建议，因此最后应创建这些索引：

CREATE INDEX :city(_id);
CREATE INDEX :street(_id);
CREATE INDEX :region(_id);
