如何在Neo4j中删除/创建数据库？ [英] How to delete/create databases in Neo4j?

问题描述

可以在图表数据库 Neo4j 中创建/删除不同的数据库吗？或者，至少，如何删除现有图的所有节点和关系，以获得干净的设置进行测试，例如使用类似 rmrel 或 rm ？

Is it possible to create/delete different databases in the graph database Neo4j like in MySQL? Or, at least, how to delete all nodes and relationships of an existing graph to get a clean setup for tests, e.g., using shell commands similar to rmrel or rm?

推荐答案

> rm -rf ，因为Neo4j不存储以下任何内容：

You can just remove the entire graph directory with rm -rf, because Neo4j is not storing anything outside that:

rm -rf data/*

此外，你可以遍历所有节点，删除它们的关系和节点本身，这可能太昂贵，只是为了测试...

Also, you can of course iterate through all nodes and delete their relationships and the nodes themselves, but that might be too costly just for testing ...
