    • 配置点、边写入规则
    • 配置 ReaderWriter
  4. 支持定时任务

规则

ID 规则

Vertex

对于Vertex ID 走 Graph ID系统,同时生成一个业务 ID ( bid )。 bid 来至于导入源,由业务系统的 ID 或者 唯一索引定制。

Edge

走Graph ID系统

Property

走Graph ID系统

Label 规则

注意:需要考虑不同数据集的情况

对于 Vertex Label 可以由客户端自行配置,在 JDBC Driver 读取器的情况下 可以由表名决定。

Edge 规则

Property 规则

支持配置映射,或直接采用文件、数据库描述

写入判断规则

对于任意数据写入,均可以配置写入前置判断 Traversal , EG :

g.V().hasLabel(label).has('bid',bid)

类图

如图 class

技术栈

  1. Gremlin
  2. vert.x-file (文件读取解析)
  3. vert.x-jdbc (读取 数据库)
  4. vert.x-shell (交互式命令行)
  5. vert.x-config (存储规则)
  6. vert.x-schedule (定时任务,用于增量导入)
