如何在单个 groovy 脚本中构建索引？

Question

当我更新了我的 janus 图模式时，我创建了一个属性键但忘记构建索引。如果我使用该属性的这个 buildIndex 运行同一段代码，那么我的数据将获得冗余数据。所以我试图直接在 gremlin 控制台中构建索引。 我试过的是

    :remote connect tinkerpop.server conf/remote.yaml
    // myScript = new File('/tmp/scripts/dbscripts/campaignTypeSchema/01_campaignTypeSchema.groovy').getText('UTF-8')
    // :> @myScript
    :> m = graph.openManagement()


    /** Getting Vertex Labels **/
    :> Campaign = m.getVertexLabel('Campaign')

    /** Vertex Properties creation **/
    :> campaignType = graph.openManagement().getPropertyKey('campaignType')

    /** Vertex supporting indexes **/
    :> graph.openManagement().buildIndex('campaignTypeByCampaign', Vertex.class).addKey(graph.openManagement().getPropertyKey('campaignType')).buildCompositeIndex()
    println "Finished updating schema"
    :remote close
    :x

但最终出现错误

    Error in /tmp/scripts/dbscripts/campaignTypeSchema/run.groovy at [9: :> Campaign = m.getVertexLabel('Campaign')] - No such property: m for class: Script36

然后我尝试直接在gremlin控制台中运行

    gremlin> :> graph.openManagement().buildIndex('campaignTypeByCampaign', Vertex.class).addKey(graph.openManagement().getPropertyKey('campaignType')).buildCompositeIndex()

为此我收到一条错误消息

    The vertex or type is not associated with this transaction [campaignType]

您需要将远程连接创建为会话：

:remote connect tinkerpop.server conf/remote.yaml session

如here 所述，否则变量状态将不会在命令之间保持不变。
