Class CacheNode

  • All Implemented Interfaces:
    Serializable, SdkPojo, ToCopyableBuilder<CacheNode.Builder,​CacheNode>
    @Generated("software.amazon.awssdk:codegen")
public final class CacheNode
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<CacheNode.Builder,​CacheNode>

    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 OSS.

    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:

    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.

    • Method Detail

      • cacheNodeId

        public final String cacheNodeId()

        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.

        Returns:
        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.

      • cacheNodeStatus

        public final String cacheNodeStatus()

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

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

      • cacheNodeCreateTime

        public final Instant cacheNodeCreateTime()

        The date and time when the cache node was created.

        Returns:
        The date and time when the cache node was created.

      • endpoint

        public final Endpoint endpoint()

        The hostname for connecting to this cache node.

        Returns:
