Struct CacheNode

pub struct CacheNode {
    pub cache_node_create_time: Option<String>,
    pub cache_node_id: Option<String>,
    pub cache_node_status: Option<String>,

}

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:

    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

    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)

    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)

    C1 node types: cache.c1.xlarge

• Memory optimized:

  • Current generation:

    R5 node types: cache.r5.large, cache.r5.xlarge, cache.r5.2xlarge, cache.r5.4xlarge, cache.r5.12xlarge, cache.r5.24xlarge

    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

    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

cache_node_create_time: Option<String>

The date and time when the cache node was created.

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 AWS account.

cache_node_status: Option<String>

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

customer_availability_zone: Option<String>

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

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.

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 Default for CacheNode

fn default() -> CacheNode

Returns the “default value” for a type.

impl PartialEq for CacheNode

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

Tests for self and other values to be equal, and is used by ==.

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

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