Studio vertexID int64支持

如图，因为js精度影响，会存在vertexID超过精度被截断

求问， Studio 目前导入图探索的时候，如何把VID 设置为 INT64类型呢？我看目前默认是string类型的id

你使用的是nebula 2.x版本的吧？

目前最新版的nebula 2.x版本，如果想让vid改为int64类型，需要在创建space的时候指定，具体参考下面的文档：

github.com

vesoft-inc/nebula-docs/blob/master/docs-2.0/3.ngql-guide/9.space-statements/1.create-space.md

# CREATE SPACE

```ngql
CREATE SPACE [IF NOT EXISTS] <graph_space_name>
    [(partition_num = <partition_number>, replica_factor = <replica_number>, charset = <charset>, collate = <collate>, vid_type = {FIXED_STRING(<N>)) | INT64}, atomic_edge={true | false}]
```

The `CREATE SPACE` statement creates a new graph space with the given name. A `SPACE` is a region that provides physically isolated graphs in Nebula Graph. An error occurs if a graph space with the same name exists if you did not specify `IF NOT EXISTS`.

## IF NOT EXISTS

You can use the `IF NOT EXISTS` keywords when creating graph spaces. These keywords automatically detect if the related graph space exists. If it does not exist, a new one is created. Otherwise, no graph space is created.

> **NOTE**: The graph space existence detection here only compares the graph space name (excluding properties).

## Graph space name

The `graph_space_name` uniquely identifies a graph space in a Nebula Graph instance.
