Neo4j在Cypher查询运行中仅使用一个核心 [英] Neo4j use only one core in Cypher query running

问题描述

当我在UI中运行Cypher查询时，服务器中只有一个核心正在运行，查询卡住或响应速度很慢.

我使用Neo4j 3.0.7社区.

有人知道我可以使用所有内核进行调整吗?

解决方案

单个Cypher查询仅限于单个线程.请参阅 tweet blog/contributor/stefan-armbruster/"rel =" nofollow noreferrer> Stefan Armbruster :

(大多数情况下)密码语句是一个事务，因此只能在一个线程上进行.

如果查询很慢，则可以使用各种技巧对其进行优化:博客文章是一个很好的起点.

When i run a Cypher query in UI, only one core in server is going up and the query gets stuck or responds very slow.

I use Neo4j 3.0.7 Community.

Someone have idea what i can tune for using all cores?

解决方案

A single Cypher query is limited to a single thread. See this tweet from late 2015 by Stefan Armbruster:

A cypher statement is (in most cases) one transaction and therefore only on one thread.

If your query is slow, you can use various tricks for optimizing it: this blog post is a good starting point.
