本文介绍Nebula Graph的数据模型。数据模型是一种组织数据并说明它们如何相互关联的模型schema

## 数据模型

Nebula Graph数据模型使用6种基本的数据模型:

- 图空间(Space)
- 图空间Space)

图空间用于隔离不同团队或者项目的数据。不同图空间的数据是相互隔离的,可以指定不同的存储副本数、权限、分片等。

- 点(Vertex)

点用来保存实体对象,特点如下:

- 点是用点标识符(`VID`)标识的。`VID`在同一图空间中唯一。VID 是一个 int64, 或者 fixed_string(N)。
- 点是用点标识符(`VID`)标识的。`VID`在同一图空间中唯一。VID 是一个 int64或者 fixed_string(N)。
- 点必须有至少一个Tag,也可以有多个Tag。但不能没有Tag。

如EdgeA_Out和EdgeA_In一样,Nebula Graph冗余了存储每条边的信息,导致存储边所需的实际空间翻倍。因为边对应的Key占用的硬盘空间较小,但Value占用的空间与属性值的长度和数量成正比,所以,当边的属性值较大或数量较多时候,硬盘空间占用量会比较大。

如果对边进行操作,为了保证两个键值对的最终一致性,可以开启[TOSS功能](../../5.configurations-and-logs/1.configurations/3.graph-config.md),开启后,会先在正向边所在的分片进行操作,然后在反向边所在分片进行操作,最后返回结果。

### 分片算法

分片策略采用**静态 Hash**的方式,即对点VID进行取模操作,同一个点的所有Tag、出边和入边信息都会存储到同一个分片,这种方式极大地提升了查询效率。
