--db-instance-parameter-group-name (string)

The name of the DB parameter group to apply to all instances of the DB cluster.

Note

When you apply a parameter group using DBInstanceParameterGroupName , parameter changes aren’t applied during the next maintenance window but instead are applied immediately.

Default: The existing name setting

Constraints:

• The DB parameter group must be in the same DB parameter group family as the target DB cluster version.

• The DBInstanceParameterGroupName parameter is only valid in combination with the AllowMajorVersionUpgrade parameter.

For more information, see Using Amazon Neptune Serverless in the Amazon Neptune User Guide .

MinCapacity -> (double)

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.

MaxCapacity -> (double)

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.

Shorthand Syntax:

MinCapacity=double,MaxCapacity=double

JSON Syntax:

{
  "MinCapacity": double,
  "MaxCapacity": double
}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

• json

• text

• table

• yaml

• yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

• on

• off

• auto

--no-sign-request (boolean)

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

• base64

• raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

(string)

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.
