我将 JanusGraph 与 Cassandra 和 ElasticSearch 后端结合使用。我使用以下脚本来创建我的架构和索引。

// Create a Janus Graph instance, according to the configuration file provided
// in the open() method below, and define the schema and index.
// This is intended to be loaded and run inside the Gremlin Console from the Janus
// Graph download. Usage :load janus-ualschema.groovy

println "\n=======================================";[]

graph = JanusGraphFactory.open("conf/janusgraph-useractivitylogs.properties")
mgmt = graph.openManagement()

图表上没有数据,我运行了脚本,没有错误。但是现在我已经插入了一些数据,每当我尝试运行任何查询时,例如: gremlin> g.V().hasLabel('浏览器').groupCount().by('browserType')

我最终收到如下警告:

15:28:00 WARN  org.janusgraph.graphdb.transaction.StandardJanusGraphTx  - 

查询需要迭代所有顶点[(~label = browser)]。为了更好的 性能、使用索引 ==>[Safari:44,Chrome:1813,IE:199,Firefox:34]

对于可能出现的问题有什么想法吗?另外,是否有任何 TinkerPop 或 JanusGraph 命令可用于查看架构及其上定义的所有索引?

预先感谢您提供的任何帮助。

最佳答案

像这样的查询:

g.V().hasLabel('browser').groupCount().by('browserType')

需要完整的顶点扫描,因为 JanusGraph 目前不允许您在顶点标签上创建索引。 Issue 283开放跟踪该增强功能。

要调查可用的索引,您可以使用此 wiki 中提到的工具.
