### Problem Type (问题类型) others (please edit later) ### Before submit - [X] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与 [FAQ](https://hugegraph.apache.org/docs/guides/faq/) 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents) ### Environment (环境信息) - Server Version: 1.0.0 (Apache Release Version) - Backend: RocksDB x nodes, HDD or SSD - OS: xx CPUs, xx G RAM, Ubuntu 2x.x / CentOS 7.x - Data Size: xx vertices, xx edges <!-- (like 1000W 点, 9000W 边) --> ### Your Question (问题描述) 首先感谢作者提供优秀的开源作品，我是一位 hugegraph 新手。在我的使用过程中，我该如何能判断出我执行的语句有没有命中索引？ 我目前知道有 `explain` 和 `profile`。通过阅读文档，我了解了 `profile` 结果的含义，但是从 `profile`中我好像不能得到是否命中索引的结果。关于 `explain` 文档看得我晕乎乎的，希望作者能给我提供帮助。再次感谢作者提供优秀的开源作品。 比如我有这样一个查询语句 ``` g.V().hasLabel('cmdb_instance_history').has('cmdb_resources_id',within('123456')).explain() ``` 结果 ```json [ { "original": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "intermediate": [ { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "ConnectiveStrategy", "category": "DecorationStrategy" }, { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "IncidentToAdjacentStrategy", "category": "OptimizationStrategy" }, { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "CountStrategy", "category": "OptimizationStrategy" }, { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "MatchPredicateStrategy", "category": "OptimizationStrategy" }, { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "FilterRankingStrategy", "category": "OptimizationStrategy" }, { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "InlineFilterStrategy", "category": "OptimizationStrategy" }, { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "AdjacentToIncidentStrategy", "category": "OptimizationStrategy" }, { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "EarlyLimitStrategy", "category": "OptimizationStrategy" }, { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "RepeatUnrollStrategy", "category": "OptimizationStrategy" }, { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "PathRetractionStrategy", "category": "OptimizationStrategy" }, { "traversal": [ "GraphStep(vertex,[])", "HasStep([~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "LazyBarrierStrategy", "category": "OptimizationStrategy" }, { "traversal": [ "HugeGraphStep(Vertex,[~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "HugeGraphStepStrategy", "category": "ProviderOptimizationStrategy" }, { "traversal": [ "HugeGraphStep(Vertex,[~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "HugeCountStepStrategy", "category": "ProviderOptimizationStrategy" }, { "traversal": [ "HugeGraphStep(Vertex,[~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "HugeVertexStepStrategy", "category": "ProviderOptimizationStrategy" }, { "traversal": [ "HugeGraphStep(Vertex,[~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "ProfileStrategy", "category": "FinalizationStrategy" }, { "traversal": [ "HugeGraphStep(Vertex,[~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ], "strategy": "StandardVerificationStrategy", "category": "VerificationStrategy" } ], "final": [ "HugeGraphStep(Vertex,[~label.eq(cmdb_instance_history), cmdb_resources_id.within([123456])])" ] } ] ``` ### Vertex/Edge example (问题点 / 边数据举例) _No response_ ### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构) _No response_ -- This is an automated message from the Apache Git Service.
