Paws::ElastiCache::DescribeReservedCacheNodes - Arguments for method DescribeReservedCacheNodes on Paws::ElastiCache


This class represents the parameters used for calling the method DescribeReservedCacheNodes on the Amazon ElastiCache service. Use the attributes of this class as arguments to method DescribeReservedCacheNodes.

You shouldn't make instances of this class. Each attribute should be used as a named argument in the call to DescribeReservedCacheNodes.


    my $elasticache = Paws->service('ElastiCache');
    my $ReservedCacheNodeMessage = $elasticache->DescribeReservedCacheNodes(
      CacheNodeType                => 'MyString',    # OPTIONAL
      Duration                     => 'MyString',    # OPTIONAL
      Marker                       => 'MyString',    # OPTIONAL
      MaxRecords                   => 1,             # OPTIONAL
      OfferingType                 => 'MyString',    # OPTIONAL
      ProductDescription           => 'MyString',    # OPTIONAL
      ReservedCacheNodeId          => 'MyString',    # OPTIONAL
      ReservedCacheNodesOfferingId => 'MyString',    # OPTIONAL

    # Results:
    my $Marker             = $ReservedCacheNodeMessage->Marker;
    my $ReservedCacheNodes = $ReservedCacheNodeMessage->ReservedCacheNodes;

    # Returns a L<Paws::ElastiCache::ReservedCacheNodeMessage> object.

Values for attributes that are native types (Int, String, Float, etc) can passed as-is (scalar values). Values for complex Types (objects) can be passed as a HashRef. The keys and values of the hashref will be used to instance the underlying object. For the AWS API documentation, see


CacheNodeType => Str

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.

  • General purpose:

    • Current generation:

      T2 node types: cache.t2.micro, cache.t2.small, cache.t2.medium

      M3 node types: cache.m3.medium, cache.m3.large, cache.m3.xlarge, cache.m3.2xlarge

      M4 node types: cache.m4.large, cache.m4.xlarge, cache.m4.2xlarge, cache.m4.4xlarge, cache.m4.10xlarge

    • Previous generation: (not recommended)

      T1 node types: cache.t1.micro

      M1 node types: cache.m1.small, cache.m1.medium, cache.m1.large, cache.m1.xlarge

  • Compute optimized:

    • Previous generation: (not recommended)

      C1 node types: cache.c1.xlarge

  • Memory optimized:

    • Current generation:

      R3 node types: cache.r3.large, cache.r3.xlarge, cache.r3.2xlarge, cache.r3.4xlarge, cache.r3.8xlarge

      R4 node types; cache.r4.large, cache.r4.xlarge, cache.r4.2xlarge, cache.r4.4xlarge, cache.r4.8xlarge, cache.r4.16xlarge

    • Previous generation: (not recommended)

      M2 node types: cache.m2.xlarge, cache.m2.2xlarge, cache.m2.4xlarge


  • All T2 instances are created in an Amazon Virtual Private Cloud (Amazon VPC).

  • Redis (cluster mode disabled): Redis backup/restore is not supported on T1 and T2 instances.

  • Redis (cluster mode enabled): Backup/restore is not supported on T1 instances.

  • Redis Append-only files (AOF) functionality is not supported for T1 or T2 instances.

Duration => Str

The duration filter value, specified in years or seconds. Use this parameter to show only reservations for this duration.

Valid Values: 1 | 3 | 31536000 | 94608000

Marker => Str

An optional marker returned from a prior request. Use this marker for pagination of results from this operation. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords.

MaxRecords => Int

The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a marker is included in the response so that the remaining results can be retrieved.

Default: 100

Constraints: minimum 20; maximum 100.

OfferingType => Str

The offering type filter value. Use this parameter to show only the available offerings matching the specified offering type.

Valid values: "Light Utilization"|"Medium Utilization"|"Heavy Utilization"

ProductDescription => Str

The product description filter value. Use this parameter to show only those reservations matching the specified product description.

ReservedCacheNodeId => Str

The reserved cache node identifier filter value. Use this parameter to show only the reservation that matches the specified reservation ID.

ReservedCacheNodesOfferingId => Str

The offering identifier filter value. Use this parameter to show only purchased reservations matching the specified offering identifier.
