DatabaseMigrationService.Client.describe_connections(**kwargs)#

Request Syntax

response = client.describe_connections(
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    MaxRecords=123,
    Marker='string'
)
Parameters:
  • Filters (list) –

    The filters applied to the connection.

    Valid filter names: endpoint-arn | replication-instance-arn

    • (dict) –

      Identifies the name and value of a filter object. This filter is used to limit the number and type of DMS objects that are returned for a particular Describe* call or similar operation. Filters are used as an optional parameter for certain API operations.

      • Name (string) – [REQUIRED]

        The name of the filter as specified for a Describe* or similar operation.

      • Values (list) – [REQUIRED]

        The filter value, which can specify one or more values used to narrow the returned results.

        • (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 the remaining results can be retrieved.

    Default: 100

    Constraints: Minimum 20, maximum 100.

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

Return type:

dict

Returns:

Response Structure

  • (dict) –

    • Marker (string) –

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

    • Connections (list) –

      A description of the connections.

      • (dict) –

        Status of the connection between an endpoint and a replication instance, including Amazon Resource Names (ARNs) and the last error message issued.

        • ReplicationInstanceArn (string) –

          The ARN of the replication instance.

        • EndpointArn (string) –

          The ARN string that uniquely identifies the endpoint.

        • Status (string) –

          The connection status. This parameter can return one of the following values:

          • "successful"

          • "testing"

          • "failed"

          • "deleting"

        • LastFailureMessage (string) –

          The error message when the connection last failed.

        • EndpointIdentifier (string) –

          The identifier of the endpoint. Identifiers must begin with a letter and must contain only ASCII letters, digits, and hyphens. They can’t end with a hyphen or contain two consecutive hyphens.

        • ReplicationInstanceIdentifier (string) –

          The replication instance identifier. This parameter is stored as a lowercase string.

Examples

Describes the status of the connections that have been made between the replication instance and an endpoint. Connections are created when you test an endpoint.
