Represents an individual cache node within a cluster. Each cache node runs its own instance of the cluster's protocol-compliant caching software - either Memcached or Redis.

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

    M6g node types (available only for Redis engine version 5.0.6 onward and for Memcached engine version 1.5.16 onward): cache.m6g.large, cache.m6g.xlarge, cache.m6g.2xlarge, cache.m6g.4xlarge, cache.m6g.8xlarge, cache.m6g.12xlarge, cache.m6g.16xlarge

    M5 node types: cache.m5.large, cache.m5.xlarge, cache.m5.2xlarge, cache.m5.4xlarge, cache.m5.12xlarge, cache.m5.24xlarge

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

    T4g node types (available only for Redis engine version 5.0.6 onward and Memcached engine version 1.5.16 onward): cache.t4g.micro, cache.t4g.small, cache.t4g.medium

    T3 node types: cache.t3.micro, cache.t3.small, cache.t3.medium

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

  • Previous generation: (not recommended. Existing clusters are still supported but creation of new clusters is not supported for these types.)

    T1 node types: cache.t1.micro

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

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

• Compute optimized:

  • Previous generation: (not recommended. Existing clusters are still supported but creation of new clusters is not supported for these types.)

    C1 node types: cache.c1.xlarge

• Memory optimized:

  • Current generation:

    R7g node types: cache.r7g.large, cache.r7g.xlarge, cache.r7g.2xlarge, cache.r7g.4xlarge, cache.r7g.8xlarge, cache.r7g.12xlarge, cache.r7g.16xlarge

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

Additional node type info

• All current generation instance types are created in Amazon VPC by default.

• Redis append-only files (AOF) are not supported for T1 or T2 instances.

• Redis Multi-AZ with automatic failover is not supported on T1 instances.

• Redis configuration variables appendonly and appendfsync are not supported on Redis version 2.8.22 and later.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

cache_node_id: Option<String>

The cache node identifier. A node ID is a numeric identifier (0001, 0002, etc.). The combination of cluster ID and node ID uniquely identifies every cache node used in a customer's Amazon account.

cache_node_status: Option<String>

The current state of this cache node, one of the following values: available, creating, rebooting, or deleting.

cache_node_create_time: Option<DateTime>

The date and time when the cache node was created.

endpoint: Option<Endpoint>

The hostname for connecting to this cache node.

parameter_group_status: Option<String>

The status of the parameter group applied to this cache node.

source_cache_node_id: Option<String>

The ID of the primary node to which this read replica node is synchronized. If this field is empty, this node is not associated with a primary cluster.

customer_availability_zone: Option<String>

The Availability Zone where this node was created and now resides.

customer_outpost_arn: Option<String>

The customer outpost ARN of the cache node.

Implementations

impl CacheNode

pub fn cache_node_id(&self) -> Option<&str>

The cache node identifier. A node ID is a numeric identifier (0001, 0002, etc.). The combination of cluster ID and node ID uniquely identifies every cache node used in a customer's Amazon account.

pub fn cache_node_status(&self) -> Option<&str>

The current state of this cache node, one of the following values: available, creating, rebooting, or deleting.

pub fn cache_node_create_time(&self) -> Option<&DateTime>

The date and time when the cache node was created.

pub fn endpoint(&self) -> Option<&Endpoint>

The hostname for connecting to this cache node.

pub fn parameter_group_status(&self) -> Option<&str>

The status of the parameter group applied to this cache node.

pub fn source_cache_node_id(&self) -> Option<&str>

The ID of the primary node to which this read replica node is synchronized. If this field is empty, this node is not associated with a primary cluster.

pub fn customer_availability_zone(&self) -> Option<&str>

The Availability Zone where this node was created and now resides.

pub fn customer_outpost_arn(&self) -> Option<&str>

The customer outpost ARN of the cache node.

impl CacheNode

pub fn builder() -> CacheNodeBuilder

Creates a new builder-style object to manufacture CacheNode.

Trait Implementations

impl Clone for CacheNode

fn clone(&self) -> CacheNode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CacheNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CacheNode

fn eq(&self, other: &CacheNode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
