在neo4j中重建标签索引 [英] Rebuild of label index in neo4j

问题描述

我的Neo4J实例突然停止工作，由于一些不相关的日志文件，我的驱动器空间不足.无论如何，现在我无法启动Neo4J，它会一遍又一遍地启动.如果我检查数据库的一致性，则会收到以下消息. (在3.3.5或3.4.1版本上均不起作用)

My Neo4J instance suddenly stopped working, I think my drive ran out of space due to some unrelated logfiles. Anyway, now I cannot start Neo4J, it start, over and over again. If i check the consistency of the database I get the following message. (It does not work neither on version 3.3.5 or 3.4.1)

WARN:标签索引未正确关闭，需要重新构建. 标签索引:neostore.labelscanstore.db 警告:索引未正确关闭，需要重新构建. Index [IndexRule [id = 1，描述符= Index(GENERAL，:label0)，provider = {key = lucene，version = 1.0}]]] 警告:索引未正确关闭，需要重新构建. Index [IndexRule [id = 3，描述符= Index(GENERAL，:label1)，provider = {key = lucene，version = 1.0}]]

WARN : Label index was not properly shutdown and rebuild is required. Label index: neostore.labelscanstore.db WARN : Index was not properly shutdown and rebuild is required. Index[ IndexRule[id=1, descriptor=Index( GENERAL, :label0 ), provider={key=lucene, version=1.0}] ] WARN : Index was not properly shutdown and rebuild is required. Index[ IndexRule[id=3, descriptor=Index( GENERAL, :label1 ), provider={key=lucene, version=1.0}] ]

我看到有一些非常古老的答案可能与某些相似的东西有关.它们仍然有效还是我应该如何解决呢?

I see that there are a few very old answers related to something that might be similar. Are they still valid or how am I supposed to solve this?

当我尝试启动Neo4J时，我会得到

When I try to start Neo4J I get

推荐答案

最近，我处于同样的起步状态.归根结底，所有索引和约束的删除和重新创建解决了我的问题.

Recently, I was in the same starting situation. At the end of the day the removal and recreation of all indices and constrains solved my issue.

DROP INDEX ON :Person(name)
DROP CONSTRAINT ON (p:Person) ASSERT p.name IS UNIQUE

CREATE INDEX ON :Person(name)
CREATE CONSTRAINT ON (p:Person) ASSERT p.name IS UNIQUE
