neo4j - 使用“apoc.load.json”将 json 加载到 Neo4j 中：数据检索不完整

问题描述

我正在尝试从 mongodb 集合中检索 json 数据并将其创建为 neo4j 中的标签。我正在使用 mongo REST API 从 mongodb 检索 json。我关注了 William Lyon 关于“MongoDB 和 Neo4j 的多语言持久性”的链接文本。

问题是我无法加载所有数据。以下是json数据的格式。

以下查询工作正常

//Load CPE collection from CVEDB of mongodb as CVE Label
CALL apoc.load.json('http://127.0.0.1:28017/cvedb/cves/') YIELD value
UNWIND value.rows as cveData
MERGE (c:CVE{_id:cveData._id['$oid']})
ON Create set c.id=cveData.id, c.cvss = cveData.cvss

输出：

Added 1000 labels, created 1000 nodes, set 2970 properties, completed after 462 ms.

问题：

> db.cves.count();
99022

集合中有 99022 条记录，为什么在我的密码查询中只创建了 1000 个节点而不是 99022？

谢谢
