restore_db_cluster_from_snapshot(**kwargs)¶Creates a new DB cluster from a DB snapshot or DB cluster snapshot.
If a DB snapshot is specified, the target DB cluster is created from the source DB snapshot with a default configuration and default security group.
If a DB cluster snapshot is specified, the target DB cluster is created from the source DB cluster restore point with the same configuration as the original source DB cluster, except that the new DB cluster is created with the default security group.

Provides the list of EC2 Availability Zones that instances in the restored DB cluster can be created in.
[REQUIRED]
The name of the DB cluster to create from the DB snapshot or DB cluster snapshot. This parameter isn't case-sensitive.
Constraints:
Example: my-snapshot-id
[REQUIRED]
The identifier for the DB snapshot or DB cluster snapshot to restore from.
You can use either the name or the Amazon Resource Name (ARN) to specify a DB cluster snapshot. However, you can use only the ARN to specify a DB snapshot.
Constraints:
[REQUIRED]
The database engine to use for the new DB cluster.
Default: The same as source
Constraint: Must be compatible with the engine of the source
The port number on which the new DB cluster accepts connections.
Constraints: Value must be 1150-65535
Default: The same port as the original DB cluster.
The name of the DB subnet group to use for the new DB cluster.
Constraints: If supplied, must match the name of an existing DBSubnetGroup.
Example: mySubnetgroup
A list of VPC security groups that the new DB cluster will belong to.
The tags to be assigned to the restored DB cluster.
Metadata assigned to an Amazon Neptune resource consisting of a key-value pair.
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 the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").
A value is the optional value of the tag. The string value can be from 1 to 256 Unicode characters in length and can't be prefixed with aws: or rds: . The string can only contain the set of Unicode letters, digits, white-space, '_', '.', '/', '=', '+', '-' (Java regex: "^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$").
The Amazon KMS key identifier to use when restoring an encrypted DB cluster from a DB snapshot or DB cluster snapshot.
The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are restoring a DB cluster with the same Amazon account that owns the KMS encryption key used to encrypt the new DB cluster, then you can use the KMS key alias instead of the ARN for the KMS encryption key.
If you do not specify a value for the KmsKeyId parameter, then the following will occur:
SnapshotIdentifier is encrypted, then the restored DB cluster is encrypted using the KMS key that was used to encrypt the DB snapshot or DB cluster snapshot.SnapshotIdentifier is not encrypted, then the restored DB cluster is not encrypted.True to enable mapping of Amazon Identity and Access Management (IAM) accounts to database accounts, and otherwise false.
Default: false
The list of logs that the restored DB cluster is to export to Amazon CloudWatch Logs.
The name of the DB cluster parameter group to associate with the new DB cluster.
Constraints:
true , tags are copied to any snapshot of the restored DB cluster that is created.Contains the scaling configuration of a Neptune Serverless DB cluster.
For more information, see Using Amazon Neptune Serverless in the Amazon Neptune User Guide .
The minimum number of Neptune capacity units (NCUs) for a DB instance in a Neptune Serverless cluster. You can specify NCU values in half-step increments, such as 8, 8.5, 9, and so on.
The maximum number of Neptune capacity units (NCUs) for a DB instance in a Neptune Serverless cluster. You can specify NCU values in half-step increments, such as 40, 40.5, 41, and so on.

Response Structure
(dict) --
DBCluster (dict) --
Contains the details of an Amazon Neptune DB cluster.
This data type is used as a response element in the DescribeDBClusters action.
AllocatedStorage (integer) --
AllocatedStoragealways returns 1, because Neptune DB cluster storage size is not fixed, but instead automatically adjusts as needed.
AvailabilityZones (list) --
Provides the list of EC2 Availability Zones that instances in the DB cluster can be created in.
BackupRetentionPeriod (integer) --
Specifies the number of days for which automatic DB snapshots are retained.
CharacterSetName (string) --
Not supported by Neptune.
DatabaseName (string) --
Contains the name of the initial database of this DB cluster that was provided at create time, if one was specified when the DB cluster was created. This same name is returned for the life of the DB cluster.
DBClusterIdentifier (string) --
Contains a user-supplied DB cluster identifier. This identifier is the unique key that identifies a DB cluster.
DBClusterParameterGroup (string) --
Specifies the name of the DB cluster parameter group for the DB cluster.
DBSubnetGroup (string) --
Specifies information on the subnet group associated with the DB cluster, including the name, description, and subnets in the subnet group.
Status (string) --
Specifies the current state of this DB cluster.
PercentProgress (string) --
Specifies the progress of the operation as a percentage.
EarliestRestorableTime (datetime) --
Specifies the earliest time to which a database can be restored with point-in-time restore.
Endpoint (string) --
Specifies the connection endpoint for the primary instance of the DB cluster.
ReaderEndpoint (string) --
The reader endpoint for the DB cluster. The reader endpoint for a DB cluster load-balances connections across the Read Replicas that are available in a DB cluster. As clients request new connections to the reader endpoint, Neptune distributes the connection requests among the Read Replicas in the DB cluster. This functionality can help balance your read workload across multiple Read Replicas in your DB cluster.
If a failover occurs, and the Read Replica that you are connected to is promoted to be the primary instance, your connection is dropped. To continue sending your read workload to other Read Replicas in the cluster, you can then reconnect to the reader endpoint.
MultiAZ (boolean) --
Specifies whether the DB cluster has instances in multiple Availability Zones.
Engine (string) --
Provides the name of the database engine to be used for this DB cluster.
EngineVersion (string) --
Indicates the database engine version.
