All Implemented Interfaces:

@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.

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

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.

    • 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:

      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:
      The hostname for connecting to this cache node.

    • parameterGroupStatus

      public final String parameterGroupStatus()

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

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

    • sourceCacheNodeId

      public final String sourceCacheNodeId()

      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.

      Returns:
      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.

    • customerAvailabilityZone

      public final String customerAvailabilityZone()

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

      Returns:

    • toBuilder

      public CacheNode.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<CacheNode.Builder,CacheNode>
      Returns:
      a builder for type T

    • builder

      public static CacheNode.Builder builder()

    • serializableBuilderClass

      public static Class<? extends CacheNode.Builder> serializableBuilderClass()

      Overrides:
      hashCode in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
