Options

--db-shard-group-identifier (string)

The user-supplied DB shard group identifier or the Amazon Resource Name (ARN) of the DB shard group. If this parameter is specified, information for only the specific DB shard group is returned. This parameter isn't case-sensitive.

Constraints:

• If supplied, must match an existing DB shard group identifier.

--filters (list)

A filter that specifies one or more DB shard groups to describe.

(structure)

A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as IDs. The filters supported by a describe operation are documented with the describe operation.

Note

Currently, wildcards are not supported in filters.

The following actions can be filtered:

• DescribeDBClusterBacktracks
• DescribeDBClusterEndpoints
• DescribeDBClusters
• DescribeDBInstances
• DescribeDBRecommendations
• DescribeDBShardGroups
• DescribePendingMaintenanceActions

Name -> (string)

The name of the filter. Filter names are case-sensitive.

Values -> (list)

One or more filter values. Filter values are case-sensitive.

(string)

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--marker (string)

An optional pagination token provided by a previous DescribeDBShardGroups request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords .

--max-records (integer)

The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a pagination token called a marker is included in the response so you can retrieve the remaining results.

Default: 100

Constraints: Minimum 20, maximum 100

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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

--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)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--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.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To describe DB shard groups

The following describe-db-shard-groups example retrieves the details of your DB shard groups.

aws rds describe-db-shard-groups

Output:

{
    "DBShardGroups": [
        {
            "DBShardGroupResourceId": "shardgroup-7bb446329da94788b3f957746example",
            "DBShardGroupIdentifier": "limitless-test-shard-grp",
            "DBClusterIdentifier": "limitless-test-cluster",
            "MaxACU": 768.0,
            "ComputeRedundancy": 0,
            "Status": "available",
            "PubliclyAccessible": true,
            "Endpoint": "limitless-test-cluster.limitless-cekycexample.us-east-2.rds.amazonaws.com"
        },
        {
            "DBShardGroupResourceId": "shardgroup-a6e3a0226aa243e2ac6c7a1234567890",

            "PubliclyAccessible": false,
            "Endpoint": "my-sv2-cluster.limitless-cekycexample.us-east-2.rds.amazonaws.com"
        }
    ]
}

For more information, see Amazon Aurora DB Clusters in the Amazon Aurora User Guide.

Output

DBShardGroups -> (list)

Contains a list of DB shard groups for the user.

(structure)

DBShardGroupResourceId -> (string)

The Amazon Web Services Region-unique, immutable identifier for the DB shard group.

DBShardGroupIdentifier -> (string)

The name of the DB shard group.

DBClusterIdentifier -> (string)

The name of the primary DB cluster for the DB shard group.

MaxACU -> (double)

The maximum capacity of the DB shard group in Aurora capacity units (ACUs).

ComputeRedundancy -> (integer)

Specifies whether to create standby instances for the DB shard group. Valid values are the following:

• 0 - Creates a single, primary DB instance for each physical shard. This is the default value, and the only one supported for the preview.
• 1 - Creates a primary DB instance and a standby instance in a different Availability Zone (AZ) for each physical shard.
• 2 - Creates a primary DB instance and two standby instances in different AZs for each physical shard.

Status -> (string)

The status of the DB shard group.

PubliclyAccessible -> (boolean)

Indicates whether the DB shard group is publicly accessible.

When the DB shard group is publicly accessible, its Domain Name System (DNS) endpoint resolves to the private IP address from within the DB shard group's virtual private cloud (VPC). It resolves to the public IP address from outside of the DB shard group's VPC. Access to the DB shard group is ultimately controlled by the security group it uses. That public access isn't permitted if the security group assigned to the DB shard group doesn't permit it.

When the DB shard group isn't publicly accessible, it is an internal DB shard group with a DNS name that resolves to a private IP address.

For more information, see CreateDBShardGroup .

This setting is only for Aurora Limitless Database.

Endpoint -> (string)

The connection endpoint for the DB shard group.

Marker -> (string)

A pagination token that can be used in a later DescribeDBClusters request.
