Redshift.Client.describe_reserved_nodes(**kwargs)

Returns the descriptions of the reserved nodes.

Request Syntax

response = client.describe_reserved_nodes(
    ReservedNodeId='string',
    MaxRecords=123,
    Marker='string'
)

Parameters:

• ReservedNodeId (string) – Identifier for the node reservation.

• MaxRecords (integer) –

  The maximum number of response records to return in each call. If the number of remaining response records exceeds the specified MaxRecords value, a value is returned in a marker field of the response. You can retrieve the next set of records by retrying the command with the returned marker value.

  Default: 100

  Constraints: minimum 20, maximum 100.

• Marker (string) – An optional parameter that specifies the starting point to return a set of response records. When the results of a DescribeReservedNodes request exceed the value specified in MaxRecords , Amazon Web Services returns a value in the Marker field of the response. You can retrieve the next set of response records by providing the returned marker value in the Marker parameter and retrying the request.
