过程

本节列出了重构和新的过程。

v3.x v4.x 注释

db.awaitIndex (indexId :: INTEGER?, timeOutSeconds = 300 :: INTEGER?) :: VOID

db.awaitIndex (indexName :: STRING?, timeOutSeconds = 300 :: INTEGER?) :: VOID

索引由名称而不是 ID 识别。

dbms.cluster.overview() :: (id :: STRING?, addresses :: LIST? OF STRING?, role :: STRING?, groups :: LIST? OF STRING?, database :: STRING?)

dbms.cluster.overview() :: (id :: STRING?, addresses :: LIST? OF STRING?, databases :: MAP?, groups :: LIST? OF STRING?)

显示所有数据库的角色。

dbms.cluster.role() :: (role :: STRING?)

dbms.cluster.role (database :: STRING?) :: (role :: STRING?)

将database名称作为参数。

dbms.cluster.routing.getRoutingTable(context :: MAP?) :: (ttl :: INTEGER?, servers :: LIST? OF MAP?)

dbms.cluster.routing.getRoutingTable (context :: MAP?, database = null :: STRING?) :: (ttl :: INTEGER?, servers :: LIST? OF MAP?)

将database名称作为参数。

db.createIndex (index :: STRING?, providerName :: STRING?) :: (index :: STRING?, providerName :: STRING?, status :: STRING?)

db.createIndex (indexName :: STRING?, labels :: LIST? OF STRING?, properties :: LIST? OF STRING?, providerName :: STRING?, config = {} :: MAP?) :: (name :: STRING?, labels :: LIST? OF STRING?, properties :: LIST? OF STRING?, providerName :: STRING?, status :: STRING?)

  • 将labels和properties作为单独的列表，而不是索引模式":Label(prop)"作为参数。

  • 它们也作为结果产生。

  • 需要indexName。

  • (可选) 将索引设置作为映射。

db.createUniquePropertyConstraint (index :: STRING?, providerName :: STRING?) :: (index :: STRING?, providerName :: STRING?, status :: STRING?)

db.createUniquePropertyConstraint (constraintName :: STRING?, labels :: LIST? OF STRING?, properties :: LIST? OF STRING?, providerName :: STRING?, config = {} :: MAP?) :: (name :: STRING?, labels :: LIST? OF STRING?, properties :: LIST? OF STRING?, providerName :: STRING?, status :: STRING?)

  • 将labels和properties作为单独的列表，而不是索引模式":Label(prop)"作为参数。

  • 它们也作为结果产生。

  • 需要constraintName。

  • (可选) 将索引设置作为映射。

db.createNodeKey (index :: STRING?, providerName :: STRING?) :: (index :: STRING?, providerName :: STRING?, status :: STRING?)

db.createNodeKey (constraintName :: STRING?, labels :: LIST? OF STRING?, properties :: LIST? OF STRING?, providerName :: STRING?, config = {} :: MAP?) :: (name :: STRING?, labels :: LIST? OF STRING?, properties :: LIST? OF STRING?, providerName :: STRING?, status :: STRING?)

  • 将labels和properties作为单独的列表，而不是索引模式":Label(prop)"作为参数。

  • 它们也作为结果产生。

  • 需要constraintName。

  • (可选) 将索引设置作为映射。

db.indexes() :: (description :: STRING?, indexName :: STRING?, tokenNames :: LIST? OF STRING?, properties :: LIST? OF STRING?, state :: STRING?, type :: STRING?, progress :: FLOAT?, provider :: MAP?, id :: INTEGER?, failureMessage :: STRING?)

db.indexes() :: (id :: INTEGER?, name :: STRING?, state :: STRING?, populationPercent :: FLOAT?, uniqueness :: STRING?, type :: STRING?, entityType :: STRING?, labelsOrTypes :: LIST? OF STRING?, properties :: LIST? OF STRING?, provider :: STRING?)

  • 将indexName重命名为name。

  • 将tokenNames重命名为labelsOrTypes。

  • 将progress重命名为populationPercent。

  • 描述实体类型（节点或关系）、唯一性和索引类型的字段type被拆分为type、uniqueness和entityType。

  • 字段provider是字符串而不是映射。

  • description被删除，取而代之的是db.schemaStatements。

  • failureMessage已移至过程db.indexDetails。

db.resampleIndex (index :: STRING?) :: VOID

db.resampleIndex (indexName :: STRING?) :: VOID

索引由名称而不是索引模式":Label(prop)"唯一标识。

db.indexDetails (indexName :: STRING?) :: (id :: INTEGER?, name :: STRING?, state :: STRING?, populationPercent :: FLOAT?, uniqueness :: STRING?, type :: STRING?, entityType :: STRING?, labelsOrTypes :: LIST? OF STRING?, properties :: LIST? OF STRING?, provider :: STRING?, indexConfig :: MAP?, failureMessage :: STRING?)

从db.indexes、indexConfig和failureMessage获取指定索引的所有信息。

db.schemaStatements () :: (name :: STRING?, type :: STRING?, createStatement :: STRING?, dropStatement :: STRING?)

获取复制此数据库的模式规则（索引和约束）所需的所有创建和删除语句。

db.ping()

客户端工具使用此过程来测试与数据库的连接。此过程在所有数据库中都可用，并且始终返回true。
