Request Syntax

response = client.describe_global_clusters(
    GlobalClusterIdentifier='string',
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    MaxRecords=123,
    Marker='string'
)
Parameters:

  • GlobalClusterIdentifier (string) – The user-supplied cluster identifier. If this parameter is specified, information from only the specific cluster is returned. This parameter isn’t case-sensitive.

  • Filters (list) –

    A filter that specifies one or more global DB clusters to describe.

    Supported filters: db-cluster-id accepts cluster identifiers and cluster Amazon Resource Names (ARNs). The results list will only include information about the clusters identified by these ARNs.

    • (dict) –

      A named set of filter values, used to return a more specific list of results. You can use a filter to match a set of resources by specific criteria, such as IDs.

      Wildcards are not supported in filters.

      • Name (string) – [REQUIRED]

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

      • Values (list) – [REQUIRED]

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

        • (string) –

  • MaxRecords (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 that you can retrieve the remaining results.

  • Marker (string) – An optional pagination token provided by a previous DescribeGlobalClusters request. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

Return type:

dict

Response Structure

  • (dict) –

    • Marker (string) –

    • GlobalClusters (list) –

      • (dict) –

        A data type representing an Amazon DocumentDB global cluster.

        • GlobalClusterIdentifier (string) –

          Contains a user-supplied global cluster identifier. This identifier is the unique key that identifies a global cluster.

        • GlobalClusterResourceId (string) –

          The Amazon Web Services RegionRegion-unique, immutable identifier for the global database cluster. This identifier is found in CloudTrail log entries whenever the KMS customer master key (CMK) for the cluster is accessed.

        • GlobalClusterArn (string) –

          The Amazon Resource Name (ARN) for the global cluster.

        • Status (string) –

          Specifies the current state of this global cluster.

        • Engine (string) –

          The Amazon DocumentDB database engine used by the global cluster.

        • EngineVersion (string) –

          Indicates the database engine version.

        • DatabaseName (string) –

          The default database name within the new global cluster.

        • StorageEncrypted (boolean) –

          The storage encryption setting for the global cluster.

        • DeletionProtection (boolean) –

          The deletion protection setting for the new global cluster.

        • GlobalClusterMembers (list) –

          The list of cluster IDs for secondary clusters within the global cluster. Currently limited to one item.

          • (dict) –

            A data structure with information about any primary and secondary clusters associated with an Amazon DocumentDB global clusters.

            • DBClusterArn (string) –

              The Amazon Resource Name (ARN) for each Amazon DocumentDB cluster.

            • Readers (list) –

              The Amazon Resource Name (ARN) for each read-only secondary cluster associated with the Amazon DocumentDB global cluster.

              • (string) –

            • IsWriter (boolean) –

              Specifies whether the Amazon DocumentDB cluster is the primary cluster (that is, has read-write capability) for the Amazon DocumentDB global cluster with which it is associated.

            • SynchronizationStatus (string) –

          A data object containing all properties for the current state of an in-process or pending switchover or failover process for this global cluster. This object is empty unless the SwitchoverGlobalCluster or FailoverGlobalCluster operation was called on this global cluster.

          • Status (string) –

            The current status of the global cluster. Possible values are as follows:

            • pending – The service received a request to switch over or fail over the global cluster. The global cluster’s primary cluster and the specified secondary cluster are being verified before the operation starts.

            • failing-over – The chosen secondary cluster is being promoted to become the new primary cluster to fail over the global cluster.

            • cancelling – The request to switch over or fail over the global cluster was cancelled and the primary cluster and the selected secondary cluster are returning to their previous states.

          • FromDbClusterArn (string) –

          • ToDbClusterArn (string) –

            The Amazon Resource Name (ARN) of the Amazon DocumentDB cluster that is currently being promoted, and which is associated with this state.

          • IsDataLossAllowed (boolean) –

            Indicates whether the operation is a global switchover or a global failover. If data loss is allowed, then the operation is a global failover. Otherwise, it’s a switchover.

        • TagList (list) –

          A list of global cluster tags.

          • (dict) –

            Metadata assigned to an Amazon DocumentDB resource consisting of a key-value pair.

            • Key (string) –

              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 contain only the set of Unicode letters, digits, white space, ‘_’, ‘.’, ‘/’, ‘=’, ‘+’, ‘-’ (Java regex: “^([\p{L}\p{Z}\p{N}_.:/=+\-]*)$”).

            • Value (string) –

              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:”.
