我们应该使用Neo4J内部ID吗? [英] Should we use the Neo4J internal id?

问题描述

我们目前正在使用Neo4j数据库，我们需要某种ID来标识节点.

We are currently working with a Neo4j database, and we need some kind of id to identify nodes.

例如，我们具有CurrentUserHasAccess(NodeId)

For example we have functions like CurrentUserHasAccess(NodeId)

在其他Stackoverflow帖子中，我读到使用内部neo4j-identifier是个坏主意，因为它会随着时间而变化.但是，当我们不使用此ID链接数据时，我认为这不是问题.

On other Stackoverflow posts I read that it's a bad idea to use the internal neo4j-identifier, because it can change over time. However I think that's not an issue when we do not use this id to link data.

但是，我似乎找不到有关此主题的任何官方消息.

However I cannot seem to find any official sources about this topic.

我想使用此ID，因为这样我们就不必担心唯一性，而更重要的是索引.

I would like to use this ID because then we do not need to worry about uniqueness, and more importantly indexing.

推荐答案

很正确，通常不建议使用内部Neo4j节点ID.这主要是因为如果删除节点，则其原始内部ID可能会被回收/重用.如果您正在寻找一种快速，优雅的解决方案，请在此处查看GraphAware框架的UUID模块 https://github.com/graphaware/neo4j-uuid ，让我们知道它是否对您有用.

You are right that it is generally not recommended to use the internal Neo4j node IDs. This is mainly because if a node gets deleted, its original internal ID may get recycled/reused. If you're looking for a quick and elegant solution to this, have a look at the UUID module of the GraphAware Framework here https://github.com/graphaware/neo4j-uuid and let us know if it works for you.
