.- Parameters:
cache_node_type (
str
) – The compute and memory capacity of the nodes in the node group (shard). 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. Changing the CacheNodeType of a Memcached instance is currently not supported. If you need to scale using Memcached, we recommend forcing a replacement update by changing theLogicalResourceId
