1.5 IndexLabel

假设已经创建好了1.1.3中的 PropertyKeys 、1.2.3中的 VertexLabels 以及 1.3.3中的 EdgeLabels

1.5.1 创建一个IndexLabel

Method & Url
POST http://localhost:8080/graphs/hugegraph/schema/indexlabels
Request Body
{
    "name": "personByCity",
    "base_type": "VERTEX_LABEL",
    "base_value": "person",
    "index_type": "SECONDARY",
    "fields": [
        "city"
    ]
}
Response Status
202
Response Body
{
    "index_label": {
        "id": 1,
        "base_type": "VERTEX_LABEL",
        "base_value": "person",
        "name": "personByCity",
        "fields": [
            "city"
        ],
        "index_type": "SECONDARY"
    },
    "task_id": 2
}

1.5.2 获取所有的IndexLabel

Method & Url
GET http://localhost:8080/graphs/hugegraph/schema/indexlabels
Response Status
200
Response Body
{
    "indexlabels": [
        {
            "id": 3,
            "base_type": "VERTEX_LABEL",
            "base_value": "software",
            "name": "softwareByPrice",
            "fields": [
                "price"
            ],
            "index_type": "RANGE"
        },
        {
            "id": 4,
            "base_type": "EDGE_LABEL",
            "base_value": "created",
            "name": "createdByDate",
            "fields": [
                "date"
            ],
            "index_type": "SECONDARY"
        },
        {
            "id": 1,
            "base_type": "VERTEX_LABEL",
            "base_value": "person",
            "name": "personByCity",
            "fields": [
                "city"
            ],
            "index_type": "SECONDARY"
        },
        {
            "id": 3,
            "base_type": "VERTEX_LABEL",
            "base_value": "person",
            "name": "personByAgeAndCity",
            "fields": [
                "age",
                "city"
            ],
            "index_type": "SECONDARY"
        }
    ]
}

1.5.3 根据name获取IndexLabel

Method & Url
GET http://localhost:8080/graphs/hugegraph/schema/indexlabels/personByCity
Response Status
200
Response Body
{
    "id": 1,
    "base_type": "VERTEX_LABEL",
    "base_value": "person",
    "name": "personByCity",
    "fields": [
        "city"
    ],
    "index_type": "SECONDARY"
}

1.5.4 根据name删除IndexLabel

删除 IndexLabel 会导致删除相关的索引数据，会产生一个异步任务

Method & Url
DELETE http://localhost:8080/graphs/hugegraph/schema/indexlabels/personByCity
Response Status
202
Response Body
{
    "task_id": 1
}

注：

可以通过GET http://localhost:8080/graphs/hugegraph/tasks/1（其中"1"是task_id）来查询异步任务的执行状态，更多异步任务RESTful API
