JanusGraph schema 声明

#获取当前索引状态
mgmt=graph.openManagement();mgmt.getGraphIndex('courtIndex1').getIndexStatus(mgmt.getPropertyKey('court')) 
#声明management对象
mgmt = graph.openManagement() 

mgmt = graph.openManagement();mgmt.getVertexLabels() #获取当前所有节点标签

mgmt.getRelationTypes(EdgeLabel.class) #获取关系的标签

mgmt = graph.openManagement(); mgmt.getRelationTypes(PropertyKey.class) #获取关系的属性

mgmt.getRelationTypes(PropertyKey.class) #获取所有属性key

mgmt = graph.openManagement();mgmt.getGraphIndexes(Vertex.class) #获取所有Index

mgmt = graph.openManagement();mgmt.awaitGraphIndexStatus(graph,'fang_publish_person_index').call();#查看当前index是否构建成

graph.dropIndex('code',Vertex)#删除index

m=graph.openManagement();i=m.getGraphIndex('fang_publish_person_index');m.updateIndex(i SchemaAction.REINDEX).get();m.commit()

mgmt = graph.openManagement();mgmt.getOpenInstances();  #获得当前服务器的所有连接实例
mgmt = graph.openManagement();mgmt.forceCloseInstance('实例id')  #删除连接实例

mgmt = graph.openManagement();mgmt.getGraphIndex('courtIndex').getIndexStatus(mgmt.getPropertyKey('court')) 获得服务器索引状态。```
