class ElastiCache.Paginator.DescribeReservedCacheNodes#

paginator = client.get_paginator('describe_reserved_cache_nodes')

paginate(**kwargs)#

Creates an iterator that will paginate through responses from ElastiCache.Client.describe_reserved_cache_nodes().

Request Syntax

response_iterator = paginator.paginate(
    ReservedCacheNodeId='string',
    ReservedCacheNodesOfferingId='string',
    CacheNodeType='string',
    Duration='string',
    ProductDescription='string',

Parameters:

ReservedCacheNodeId (string) – The reserved cache node identifier filter value. Use this parameter to show only the reservation that matches the specified reservation ID.
ReservedCacheNodesOfferingId (string) – The offering identifier filter value. Use this parameter to show only purchased reservations matching the specified offering identifier.
CacheNodeType (string) –
The cache node type filter value. Use this parameter to show only those reservations matching the specified cache node type.

The following node types are supported by ElastiCache. Generally speaking, the current generation types provide more memory and computational power at lower cost when compared to their equivalent previous generation counterparts.
