The AuthorizeCacheSecurityGroupIngress operation allows network ingress to a cache security group. Applications using ElastiCache must be running on Amazon EC2, and Amazon EC2 security groups are used as the authorization mechanism.

NOTE: You cannot authorize ingress from an Amazon EC2 security group in one Region to an ElastiCache cluster in another Region.

Describes an availability zone in which the cache cluster is launched.

Contains all of the attributes of a specific cache cluster.

Provides all of the details about a particular cache engine version.

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

A parameter that has a different value for each cache node type it is applied to. For example, in a Redis cache cluster, a cache.m1.large cache node type would have a larger maxmemory value than a cache.m1.small type.

The CopySnapshot operation makes a copy of an existing snapshot.

The CreateCacheCluster operation creates a new cache cluster. All nodes in the cache cluster run the same protocol-compliant cache engine software - either Memcached or Redis.

The CreateCacheParameterGroup operation creates a new cache parameter group. A cache parameter group is a collection of parameters that you apply to all of the nodes in a cache cluster.

The CreateCacheSecurityGroup operation creates a new cache security group. Use a cache security group to control access to one or more cache clusters.

Cache security groups are only used when you are creating a cluster outside of an Amazon Virtual Private Cloud (VPC). If you are creating a cluster inside of a VPC, use a cache subnet group instead. For more information, see CreateCacheSubnetGroup .

The CreateCacheSubnetGroup operation creates a new cache subnet group.

Use this parameter only when you are creating a cluster in an Amazon Virtual Private Cloud (VPC).

The CreateReplicationGroup operation creates a replication group. A replication group is a collection of cache clusters, where one of the clusters is a read/write primary and the other clusters are read-only replicas. Writes to the primary are automatically propagated to the replicas.

When you create a replication group, you must specify an existing cache cluster that is in the primary role. When the replication group has been successfully created, you can add one or more read replica replicas to it, up to a total of five read replicas.

The CreateSnapshot operation creates a copy of an entire cache cluster at a specific moment in time.

The DeleteCacheCluster operation deletes a previously provisioned cache cluster. DeleteCacheCluster deletes all associated cache nodes, node endpoints and the cache cluster itself. When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the cache cluster; you cannot cancel or revert this operation.

The DeleteCacheParameterGroup operation deletes the specified cache parameter group. You cannot delete a cache parameter group if it is associated with any cache clusters.

The DeleteCacheSecurityGroup operation deletes a cache security group.

NOTE:You cannot delete a cache security group if it is associated with any cache clusters.

The DeleteCacheSubnetGroup operation deletes a cache subnet group.

NOTE:You cannot delete a cache subnet group if it is associated with any cache clusters.

The DeleteReplicationGroup operation deletes an existing replication group. By default, this operation deletes the entire replication group, including the primary cache cluster and all of the read replicas. You can optionally delete only the read replicas, while retaining the primary cache cluster.

When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the selected resources; you cannot cancel or revert this operation.

The DeleteSnapshot operation deletes an existing snapshot. When you receive a successful response from this operation, ElastiCache immediately begins deleting the snapshot; you cannot cancel or revert this operation.

The DescribeCacheClusters operation returns information about all provisioned cache clusters if no cache cluster identifier is specified, or about a specific cache cluster if a cache cluster identifier is supplied.

By default, abbreviated information about the cache clusters(s) will be returned. You can use the optional ShowDetails flag to retrieve detailed information about the cache nodes associated with the cache clusters. These details include the DNS address and port for the cache node endpoint.

If the cluster is in the CREATING state, only cluster level information will be displayed until all of the nodes are successfully provisioned.

If the cluster is in the DELETING state, only cluster level information will be displayed.

If cache nodes are currently being added to the cache cluster, node endpoint information and creation time for the additional nodes will not be displayed until they are completely provisioned. When the cache cluster state is available , the cluster is ready for use.

If cache nodes are currently being removed from the cache cluster, no endpoint information for the removed nodes is displayed.

Represents the output of a DescribeCacheClusters operation.

The DescribeCacheEngineVersions operation returns a list of the available cache engines and their versions.

Represents the output of a DescribeCacheEngineVersions operation.

The DescribeCacheParameterGroups operation returns a list of cache parameter group descriptions. If a cache parameter group name is specified, the list will contain only the descriptions for that group.

Represents the output of a DescribeCacheParameterGroups operation.

The DescribeCacheParameters operation returns the detailed parameter list for a particular cache parameter group.

Represents the output of a DescribeCacheParameters operation.

The DescribeCacheSecurityGroups operation returns a list of cache security group descriptions. If a cache security group name is specified, the list will contain only the description of that group.

Represents the output of a DescribeCacheSecurityGroups operation.

The DescribeCacheSubnetGroups operation returns a list of cache subnet group descriptions. If a subnet group name is specified, the list will contain only the description of that group.

Represents the output of a DescribeCacheSubnetGroups operation.

The DescribeEngineDefaultParameters operation returns the default engine and system parameter information for the specified cache engine.

The DescribeEvents operation returns events related to cache clusters, cache security groups, and cache parameter groups. You can obtain events specific to a particular cache cluster, cache security group, or cache parameter group by providing the name as a parameter.

By default, only the events occurring within the last hour are returned; however, you can retrieve up to 14 days' worth of events if necessary.

Represents the output of a DescribeEvents operation.

The DescribeReplicationGroups operation returns information about a particular replication group. If no identifier is specified, DescribeReplicationGroups returns information about all replication groups.

The PurchaseReservedCacheNodesOffering operation allows you to purchase a reserved cache node offering.

The RebootCacheCluster operation reboots some, or all, of the cache cluster nodes within a provisioned cache cluster. This API will apply any modified cache parameter groups to the cache cluster. The reboot action takes place as soon as possible, and results in a momentary outage to the cache cluster. During the reboot, the cache cluster status is set to REBOOTING.

The reboot causes the contents of the cache (for each cache cluster node being rebooted) to be lost.

When the reboot is complete, a cache cluster event is created.
