The cache node type filter value. Use this parameter to show only those reservations matching the specified cache node type.

Valid node types are as follows:

General purpose: Current generation: 'cache.t2.micro', 'cache.t2.small', 'cache.t2.medium', 'cache.m3.medium', 'cache.m3.large', 'cache.m3.xlarge', 'cache.m3.2xlarge' Previous generation: 'cache.t1.micro', 'cache.m1.small', 'cache.m1.medium', 'cache.m1.large', 'cache.m1.xlarge' Compute optimized: 'cache.c1.xlarge' Memory optimized Current generation: 'cache.r3.large', 'cache.r3.xlarge', 'cache.r3.2xlarge', 'cache.r3.4xlarge', 'cache.r3.8xlarge' Previous generation: 'cache.m2.xlarge', 'cache.m2.2xlarge', 'cache.m2.4xlarge' Notes:

All t2 instances are created in an Amazon Virtual Private Cloud (VPC). Redis backup/restore is not supported for t2 instances. Redis Append-only files (AOF) functionality is not supported for t1 or t2 instances. For a complete listing of cache node types and specifications, see Amazon ElastiCache Product Features and Details and Cache NodeType-Specific Parameters for Memcached or Cache Node Type-Specific Parametersfor Redis.

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'

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

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.

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"'

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

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

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