)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.
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:
M7g node types: cache.m7g.large, cache.m7g.xlarge,
cache.m7g.2xlarge, cache.m7g.4xlarge, cache.m7g.8xlarge,
cache.m7g.12xlarge, cache.m7g.16xlarge
For region availability, see Supported Node Types

Additional node type info
All current generation instance types are created in Amazon VPC by default.
Redis OSS append-only files (AOF) are not supported for T1 or T2 instances.
Redis OSS Multi-AZ with automatic failover is not supported on T1 instances.
Redis OSS configuration variables appendonly and appendfsync are
not supported on Redis OSS version 2.8.22 and later.
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
The product description filter value. Use this parameter to show only those reservations matching the specified product description.
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"|"All Upfront"|"Partial Upfront"| "No Upfront"
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.
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.
