Parameters:
  DbInstanceType:
    Description: Neptune DB instance type
    Type: String
    Default: db.r5.large
Resources:
  NeptuneDBClusterParameterGroup:
    Type: 'AWS::Neptune::DBClusterParameterGroup'
    Properties:
      Family: neptune1
      Description: 'NeptuneDBClusterParameterGroup with family neptune1'
      Parameters:
        neptune_enable_audit_log: 0
  NeptuneDBParameterGroup:
    Type: 'AWS::Neptune::DBParameterGroup'
    Properties:
      Family: neptune1
      Description: 'NeptuneDBParameterGroup with family neptune1'
      Parameters:
        neptune_query_timeout: 20000
  NeptuneDBCluster:
    Type: 'AWS::Neptune::DBCluster'
    Properties:
      EngineVersion: 1.1.1.0
      DBClusterParameterGroupName:
        Ref: NeptuneDBClusterParameterGroup
    DependsOn:
      - NeptuneDBClusterParameterGroup
  CustomNeptuneDBInstance:
    Type: 'AWS::Neptune::DBInstance'
    Properties:
      DBClusterIdentifier:
        Ref: NeptuneDBCluster
      DBInstanceClass:
        Ref: DbInstanceType
      DBParameterGroupName:
        Ref: NeptuneDBParameterGroup
    DependsOn:
      - NeptuneDBCluster
      - NeptuneDBParameterGroup
  DefaultNeptuneDBInstance:
    Type: 'AWS::Neptune::DBInstance'
    Properties:
      DBClusterIdentifier:
        Ref: NeptuneDBCluster
      DBInstanceClass:
        Ref: DbInstanceType
    DependsOn:
      - NeptuneDBCluster
Outputs:
  DBClusterId:
    Description: Neptune Cluster Identifier
    Value:
      Ref: NeptuneDBCluster

  • 對於自訂叢集參數群組，請將 DBClusterParameterGroup 系列更新為對應至新引擎版本的系列，即 neptune1.2。

  • 對於預設叢集參數群組，請將 DBClusterParameterGroup 更新為對應至新引擎版本的預設值，即 default.neptune1.2。

  • 對於附加至 DBCluster 的每個 DBInstance，請將預設 DBParameterGroup 更新為新引擎版本使用的系列中的參數群組 (此處的 default.neptune1.2)，並將自訂參數群組更新為使用新引擎版本所支援系列的參數群組 (此處的 neptune1.2)。

  • 將 DBInstanceParameterGroupName 屬性設定為新引擎版本支援的系列中的參數群組。

範本應如下所示：
