    The number of CPU cores and the number of threads per core for the DB instance class of the DB instance when the DB snapshot was created.
    - (dict) –
      
      Contains the processor features of a DB instance class.
      
      To specify the number of CPU cores, use the coreCount feature name for the Name parameter. To specify the number of threads per core, use the threadsPerCore feature name for the Name parameter.
      
      You can set the processor features of the DB instance class for a DB instance when you call one of the following actions:
      - CreateDBInstance
      - ModifyDBInstance
      - RestoreDBInstanceFromDBSnapshot
      - RestoreDBInstanceFromS3
      - RestoreDBInstanceToPointInTime
      You can view the valid processor values for a particular instance class by calling the DescribeOrderableDBInstanceOptions action and specifying the instance class for the DBInstanceClass parameter.
      
      In addition, you can use the following actions for DB instance class processor information:
      - DescribeDBInstances
      - DescribeDBSnapshots
      - DescribeValidDBInstanceModifications
      If you call DescribeDBInstances, ProcessorFeature returns non-null values only if the following conditions are met:
      - You are accessing an Oracle DB instance.
      - Your Oracle DB instance class supports configuring the number of CPU cores and threads per core.
      - The current number CPU cores and threads is set to a non-default value.
      For more information, see Configuring the Processor of the DB Instance Class in the *Amazon RDS User Guide. *
      - Name (string) –
        
        The name of the processor feature. Valid names are coreCount and threadsPerCore.
      - Value (string) –
        
        The value of a processor feature name.
  - DbiResourceId (string) –
    
    The identifier for the source DB instance, which can’t be changed and which is unique to an Amazon Web Services Region.
  - TagList (list) –
    
    A list of tags. For more information, see Tagging Amazon RDS Resources in the Amazon RDS User Guide.
    - (dict) –
      
      Metadata assigned to an Amazon RDS resource consisting of a key-value pair.
      
      For more information, see Tagging Amazon RDS Resources in the Amazon RDS User Guide.
      - Key (string) –
        
        A key is the required name of the tag. The string value can be from 1 to 128 Unicode characters in length and can’t be prefixed with aws: or rds:. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘:’, ‘/’, ‘=’, ‘+’, ‘-’, ‘@’ (Java regex: “^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$”).
      - Value (string) –
        
        A value is the optional value of the tag. The string value can be from 1 to 256 Unicode characters in length and can’t be prefixed with aws: or rds:. The string can only contain only the set of Unicode letters, digits, white-space, ‘_’, ‘.’, ‘:’, ‘/’, ‘=’, ‘+’, ‘-’, ‘@’ (Java regex: “^([\p{L}\p{Z}\p{N}_.:/=+\-@]*)$”).
  - OriginalSnapshotCreateTime (datetime) –
    
    Specifies the time of the CreateDBSnapshot operation in Coordinated Universal Time (UTC). Doesn’t change when the snapshot is copied.
  - SnapshotDatabaseTime (datetime) –
    
    The timestamp of the most recent transaction applied to the database that you’re backing up. Thus, if you restore a snapshot, SnapshotDatabaseTime is the most recent transaction in the restored DB instance. In contrast, originalSnapshotCreateTime specifies the system time that the snapshot completed.
    
    If you back up a read replica, you can determine the replica lag by comparing SnapshotDatabaseTime with originalSnapshotCreateTime. For example, if originalSnapshotCreateTime is two hours later than SnapshotDatabaseTime, then the replica lag is two hours.
  - SnapshotTarget (string) –
    
    Specifies where manual snapshots are stored: Amazon Web Services Outposts or the Amazon Web Services Region.
  - StorageThroughput (integer) –
    
    Specifies the storage throughput for the DB snapshot.
