存储过程在Neo4j中 [英] Stored procedure in Neo4j

问题描述

我想知道是否有与存储过程等效的Neo4j? 研究此内容时，我遇到了events，但是我发现它们更像是触发器，而不是存储过程.

I wanted to know if there is any Neo4j equivalent of a stored procedure? When I researched this, I came across events, but I found them more like triggers and not stored procedures.

推荐答案

从3.0版开始，存储过程可以通过Cypher语言作为CALLABLE功能使用.

Stored procedures are available as capabilities CALLABLE from the Cypher language since version 3.0

编辑

随着Neo4J 3.0于16年4月发布，该存储过程成为Apache 2.0许可的正式存储库.

As Neo4J 3.0 has been released in April'16, the stored procedure became an official, Apache 2.0 licensed, repository.

可用的过程从数据处理/导入到空间和复杂图形算法(例如页面排名，Dijkstra，社区检测，中间性，紧密性等)

Available procedures range from data manipulation/import to Spatial and complex graph algorithms (es. Page Rank, Dijkstra, Community detection, betweenness centrality , closeness centrality, etc)
