在janusgraph键空间下的cassandra中缺少vertex_ids表？

问题描述

与cassandra一起使用时，Titan图会在 titan键空间下创建一个表 vertex_ids。但是当使用janus时，我似乎无法在janusgrpah键空间下找到 vertex_ids表。我也阅读了文档，其中描述了值的存储方式，但没有说明在哪些表下。

Titan graph when used with cassandra creates a table "vertex_ids" under the "titan" keyspace. But when working with janus , I can't seem to find the "vertex_ids" table under the 'janusgrpah' keyspace. Also I read the documentation where they describe how the values are stored but it doesn't tell under which tables.

推荐答案

JanusGraph开始了来自TitanDB 1.0.0。两者都使用以下cassandra表：

JanusGraph started from TitanDB 1.0.0. Both are using these below cassandra tables :

• edgestore：将顶点，属性和边存储为邻接列表


• graphindex：顶点和边属性的内置索引


• titan_ids（TitanDB）janusgraph_ids（JanusGraph）：商店ID块


• txlog：商店事务日志


• 系统日志：存储系统日志


• system_properties：存储系统属性


• edgestore_lock_：用于锁定边缘存储表


• graphindex_lock_：用于锁定graphindex表


• system_properties_lock_：用于锁定system_properties表

• edgestore : Store Vertex, Property and Edges as Adjacency List
• graphindex : Builtin indexes for vertex and edge properties
• titan_ids (TitanDB) janusgraph_ids (JanusGraph) : Store ID Block
• txlog : Store Transaction Log
• systemlog : Store System Log
• system_properties : Store System Properties
• edgestore_lock_ : Used to lock edgestore table
• graphindex_lock_ : Used to lock graphindex table
• system_properties_lock_ : Used to lock system_properties table
