我有一个约束：

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

Answer 1

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);

提高Neo4j密码查询性能
