将边缘加载到neo4j需要花费太多时间

Question

您好我正在尝试将边缘文件加载到每个大约80000条记录的neo4j。 我正在使用：

USING PERIODIC COMMIT 500 LOAD CSV WITH HEADERS FROM 
"file:///EdgesWriterSong_wrote.csv" AS csvLine
MATCH (writer:Writer { id: toInt(csvLine.WriterId),(songs:Songs { SongId: toInt(csvLine.SongId)
CREATE (writer)-[r:Wrote]->(songs)

加载时间过长。请问有更快的方法吗？

Answer 1

您的查询有语法错误，但我假设您的实际代码如下所示：

node-sass -rw scssFiles -o cssOutputFiles

这种简单查询缓慢的最明显原因是您尚未为USING PERIODIC COMMIT 500 LOAD CSV WITH HEADERS FROM "file:///EdgesWriterSong_wrote.csv" AS csvLine MATCH (writer:Writer { id: toInt(csvLine.WriterId) }), (songs:Songs { SongId: toInt(csvLine.SongId) }) CREATE (writer)-[r:Wrote]->(songs); 和:Writer(id)创建indexes。通过运行这两个查询（一次一个）来做到这一点：

Songs(SongId)
