AWSSDK.ElastiCache

Amazon ElastiCache

Amazon ElastiCache is a web service that makes it easier to set up, operate, and scale a distributed cache in the cloud.

With ElastiCache, customers get all of the benefits of a high-performance, in-memory cache with less of the administrative burden involved in launching and managing a distributed cache. The service makes setup, scaling, and cluster failure handling much simpler than in a self-managed cache deployment.

In addition, through integration with Amazon CloudWatch, customers get enhanced visibility into the key performance statistics associated with their cache and can receive alarms if a part of their cache runs hot.

AddTagsToResource Operation

Adds up to 50 cost allocation tags to the named resource. A cost allocation tag is a key-value pair where the key and value are case-sensitive. You can use cost allocation tags to categorize and track your AWS costs.

When you apply tags to your ElastiCache resources, AWS generates a cost allocation report as a comma-separated value (CSV) file with your usage and costs aggregated by your tags. You can apply tags that represent business categories (such as cost centers, application names, or owners) to organize your costs across multiple services. For more information, see Using Cost Allocation Tags in Amazon ElastiCache in the ElastiCache User Guide.

Arguments

ResourceName = ::StringRequired

The Amazon Resource Name (ARN) of the resource to which the tags are to be added, for example arn:aws:elasticache:us-west-2:0123456789:cluster:myCluster or arn:aws:elasticache:us-west-2:0123456789:snapshot:mySnapshot. ElastiCache resources are cluster and snapshot.

For more information about ARNs, see Amazon Resource Names (ARNs) and AWS Service Namespaces.

Tags = [[ ... ], ...]Required

A list of cost allocation tags to be added to this resource. A tag is a key-value pair. A tag key must be accompanied by a tag value.

 Tags = [[
        "Key" =>  ::String,
        "Value" =>  ::String
    ], ...]

Returns

TagListMessage

Exceptions

CacheClusterNotFoundFault, SnapshotNotFoundFault, TagQuotaPerResourceExceeded or InvalidARNFault.

The cache security group that allows network ingress.

EC2SecurityGroupName = ::StringRequired

The Amazon EC2 security group to be authorized for ingress to the cache security group.

EC2SecurityGroupOwnerId = ::StringRequired

The AWS account number of the Amazon EC2 security group owner. Note that this is not the same thing as an AWS access key ID - you must provide a valid AWS account number for this parameter.

Returns

AuthorizeCacheSecurityGroupIngressResult

Exceptions

CacheSecurityGroupNotFoundFault, InvalidCacheSecurityGroupStateFault, AuthorizationAlreadyExistsFault, InvalidParameterValueException or InvalidParameterCombinationException.

CopySnapshot Operation

Makes a copy of an existing snapshot.

Note

This operation is valid for Redis only.

Important

Users or groups that have permissions to use the CopySnapshot operation can create their own Amazon S3 buckets and copy snapshots to it. To control access to your snapshots, use an IAM policy to control who has the ability to use the CopySnapshot operation. For more information about using IAM to control the use of ElastiCache operations, see Exporting Snapshots and Authentication & Access Control.

You could receive the following error messages.

Error Messages

  • Error Message: The S3 bucket %s is outside of the region.

    Solution: Create an Amazon S3 bucket in the same region as your snapshot. For more information, see Step 1: Create an Amazon S3 Bucket in the ElastiCache User Guide.

  • Error Message: The S3 bucket %s does not exist.

    Solution: Create an Amazon S3 bucket in the same region as your snapshot. For more information, see Step 1: Create an Amazon S3 Bucket in the ElastiCache User Guide.

  • Error Message: The S3 bucket %s is not owned by the authenticated user.

    Solution: Create an Amazon S3 bucket in the same region as your snapshot. For more information, see Step 1: Create an Amazon S3 Bucket in the ElastiCache User Guide.

  • Error Message: The authenticated user does not have sufficient permissions to perform the desired activity.

    Solution: Contact your system administrator to get the needed permissions.

  • Error Message: The S3 bucket %s already contains an object with key %s.

    Solution: Give the TargetSnapshotName a new and unique value. If exporting a snapshot, you could alternatively create a new Amazon S3 bucket and use this same value for TargetSnapshotName.

  • Error Message: ElastiCache has not been granted READ permissions %s on the S3 Bucket.

    Solution: Add List and Read permissions on the bucket. For more information, see Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket in the ElastiCache User Guide.

  • Error Message: ElastiCache has not been granted WRITE permissions %s on the S3 Bucket.

    Solution: Add Upload/Delete permissions on the bucket. For more information, see Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket in the ElastiCache User Guide.

  • Error Message: ElastiCache has not been granted READ_ACP permissions %s on the S3 Bucket.

    Solution: Add View Permissions on the bucket. For more information, see Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket in the ElastiCache User Guide.

Arguments

SourceSnapshotName = ::StringRequired

The name of an existing snapshot from which to make a copy.

TargetSnapshotName = ::StringRequired

A name for the snapshot copy. ElastiCache does not permit overwriting a snapshot, therefore this name must be unique within its context - ElastiCache or an Amazon S3 bucket if exporting.

TargetBucket = ::String

The Amazon S3 bucket to which the snapshot is exported. This parameter is used only when exporting a snapshot for external access.

When using this parameter to export a snapshot, be sure Amazon ElastiCache has the needed permissions to this S3 bucket. For more information, see Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket in the Amazon ElastiCache User Guide.

For more information, see Exporting a Snapshot in the Amazon ElastiCache User Guide.

Returns

CopySnapshotResult

Exceptions

SnapshotAlreadyExistsFault, SnapshotNotFoundFault, SnapshotQuotaExceededFault, InvalidSnapshotStateFault, InvalidParameterValueException or InvalidParameterCombinationException.

elasticache([::AWSConfig], "CreateReplicationGroup", ReplicationGroupId=, ReplicationGroupDescription=, <keyword arguments>)

CreateReplicationGroup Operation

Creates a Redis (cluster mode disabled) or a Redis (cluster mode enabled) replication group.

A Redis (cluster mode disabled) replication group is a collection of clusters, where one of the clusters is a read/write primary and the others are read-only replicas. Writes to the primary are asynchronously propagated to the replicas.

A Redis (cluster mode enabled) replication group is a collection of 1 to 15 node groups (shards). Each node group (shard) has one read/write primary node and up to 5 read-only replica nodes. Writes to the primary are asynchronously propagated to the replicas. Redis (cluster mode enabled) replication groups partition the data across node groups (shards).

When a Redis (cluster mode disabled) replication group has been successfully created, you can add one or more read replicas to it, up to a total of 5 read replicas. You cannot alter a Redis (cluster mode enabled) replication group after it has been created. However, if you need to increase or decrease the number of node groups (console: shards), you can avail yourself of ElastiCache for Redis' enhanced backup and restore. For more information, see Restoring From a Backup with Cluster Resizing in the ElastiCache User Guide.

Note

This operation is valid for Redis only.

Arguments

ReplicationGroupId = ::StringRequired

The replication group identifier. This parameter is stored as a lowercase string.

Constraints:

  • A name must contain from 1 to 20 alphanumeric characters or hyphens.

  • The first character must be a letter.

  • A name cannot end with a hyphen or contain two consecutive hyphens.

ReplicationGroupDescription = ::StringRequired

A user-created description for the replication group.

PrimaryClusterId = ::String

The identifier of the cluster that serves as the primary for this replication group. This cluster must already exist and have a status of available.

This parameter is not required if NumCacheClusters, NumNodeGroups, or ReplicasPerNodeGroup is specified.

AutomaticFailoverEnabled = ::Bool

Specifies whether a read-only replica is automatically promoted to read/write primary if the existing primary fails.

If true, Multi-AZ is enabled for this replication group. If false, Multi-AZ is disabled for this replication group.

AutomaticFailoverEnabled must be enabled for Redis (cluster mode enabled) replication groups.

Default: false

Amazon ElastiCache for Redis does not support Multi-AZ with automatic failover on:

  • Redis versions earlier than 2.8.6.

  • Redis (cluster mode disabled): T1 and T2 cache node types.

  • Redis (cluster mode enabled): T1 node types.

NumCacheClusters = ::Int

The number of clusters this replication group initially has.

This parameter is not used if there is more than one node group (shard). You should use ReplicasPerNodeGroup instead.

If AutomaticFailoverEnabled is true, the value of this parameter must be at least 2. If AutomaticFailoverEnabled is false you can omit this parameter (it will default to 1), or you can explicitly set it to a value between 2 and 6.

The maximum permitted value for NumCacheClusters is 6 (primary plus 5 replicas).

PreferredCacheClusterAZs = [::String, ...]

ListAllowedNodeTypeModifications Operation

Lists all available node types that you can scale your Redis cluster's or replication group's current node type up to.

When you use the ModifyCacheCluster or ModifyReplicationGroup operations to scale up your cluster or replication group, the value of the CacheNodeType parameter must be one of the node types returned by this operation.

Arguments

CacheClusterId = ::String

The name of the cluster you want to scale up to a larger node instanced type. ElastiCache uses the cluster id to identify the current node type of this cluster and from that to create a list of node types you can scale up to.

Important

You must provide a value for either the CacheClusterId or the ReplicationGroupId.

ReplicationGroupId = ::String

The name of the replication group want to scale up to a larger node type. ElastiCache uses the replication group id to identify the current node type being used by this replication group, and from that to create a list of node types you can scale up to.

elasticache([::AWSConfig], "ListTagsForResource", arguments::Dict)
elasticache([::AWSConfig], "ListTagsForResource", ResourceName=)

ListTagsForResource Operation

You can have a maximum of 50 cost allocation tags on an ElastiCache resource. For more information, see Using Cost Allocation Tags in Amazon ElastiCache.

Arguments

ResourceName = ::StringRequired

The Amazon Resource Name (ARN) of the resource for which you want the list of tags, for example arn:aws:elasticache:us-west-2:0123456789:cluster:myCluster or arn:aws:elasticache:us-west-2:0123456789:snapshot:mySnapshot.

elasticache([::AWSConfig], "ModifyCacheCluster", CacheClusterId=, <keyword arguments>)

ModifyCacheCluster Operation

Modifies the settings for a cluster. You can use this operation to change one or more cluster configuration parameters by specifying the parameters and the new values.

Arguments

CacheClusterId = ::StringRequired

The cluster identifier. This value is stored as a lowercase string.

NumCacheNodes = ::Int

The number of cache nodes that the cluster should have. If the value for NumCacheNodes is greater than the sum of the number of current cache nodes and the number of cache nodes pending creation (which may be zero), more nodes are added. If the value is less than the number of existing cache nodes, nodes are removed. If the value is equal to the number of current cache nodes, any pending add or remove requests are canceled.

If you are removing cache nodes, you must use the CacheNodeIdsToRemove parameter to provide the IDs of the specific cache nodes to remove.

For clusters running Redis, this value must be 1. For clusters running Memcached, this value must be between 1 and 20.

Note

Adding or removing Memcached cache nodes can be applied immediately or as a pending operation (see ApplyImmediately).

A pending operation to modify the number of cache nodes in a cluster during its maintenance window, whether by adding or removing nodes in accordance with the scale out architecture, is not queued. The customer's latest request to add or remove nodes to the cluster overrides any previous pending operations to modify the number of cache nodes in the cluster. For example, a request to remove 2 nodes would override a previous pending operation to remove 3 nodes. Similarly, a request to add 2 nodes would override a previous pending operation to remove 3 nodes and vice versa. As Memcached cache nodes may now be provisioned in different Availability Zones with flexible cache node placement, a request to add nodes does not automatically override a previous pending operation to add nodes. The customer can modify the previous pending operation to add more nodes or explicitly cancel the pending request and retry the new request. To cancel pending operations to modify the number of cache nodes in a cluster, use the ModifyCacheCluster request and set NumCacheNodes equal to the number of cache nodes currently in the cluster.

CacheNodeIdsToRemove = [::String, ...]

A list of cache node IDs to be removed. A node ID is a numeric identifier (0001, 0002, etc.). This parameter is only valid when NumCacheNodes is less than the existing number of cache nodes. The number of cache node IDs supplied in this parameter must match the difference between the existing number of cache nodes in the cluster or pending cache nodes, whichever is greater, and the value of NumCacheNodes in the request.

For example: If you have 3 active cache nodes, 7 pending cache nodes, and the number of cache nodes in this ModifyCacheCluster call is 5, you must list 2 (7 - 5) cache node IDs to remove.

AZMode = "single-az" or "cross-az"

Specifies whether the new nodes in this Memcached cluster are all created in a single Availability Zone or created across multiple Availability Zones.

Valid values: single-az | cross-az.

This option is only supported for Memcached clusters.

Note

You cannot specify single-az if the Memcached cluster already has cache nodes in different Availability Zones. If cross-az is specified, existing Memcached nodes remain in their current Availability Zone.

Only newly created nodes are located in different Availability Zones. For instructions on how to move existing Memcached nodes to different Availability Zones, see the Availability Zone Considerations section of Cache Node Considerations for Memcached.

NewAvailabilityZones = [::String, ...]

The list of Availability Zones where the new Memcached cache nodes are created.

This parameter is only valid when NumCacheNodes in the request is greater than the sum of the number of active cache nodes and the number of cache nodes pending creation (which may be zero). The number of Availability Zones supplied in this list must match the cache nodes being added in this request.

This option is only supported on Memcached clusters.

Scenarios:

  • Scenario 1: You have 3 active nodes and wish to add 2 nodes. Specify NumCacheNodes=5 (3 + 2) and optionally specify two Availability Zones for the two new nodes.

  • Scenario 2: You have 3 active nodes and 2 nodes pending creation (from the scenario 1 call) and want to add 1 more node. Specify NumCacheNodes=6 ((3 + 2) + 1) and optionally specify an Availability Zone for the new node.

  • Scenario 3: You want to cancel all pending operations. Specify NumCacheNodes=3 to cancel all pending operations.

The Availability Zone placement of nodes pending creation cannot be modified. If you wish to cancel any nodes pending creation, add 0 nodes by setting NumCacheNodes to the number of current nodes.

If cross-az is specified, existing Memcached nodes remain in their current Availability Zone. Only newly created nodes can be located in different Availability Zones. For guidance on how to move existing Memcached nodes to different Availability Zones, see the Availability Zone Considerations section of Cache Node Considerations for Memcached.

Impact of new add/remove requests upon pending requests

  • Scenario-1

    • Pending Action: Delete

    • New Request: Delete

    • Result: The new delete, pending or immediate, replaces the pending delete.

  • Scenario-2

    • Pending Action: Delete

    • New Request: Create

    • Result: The new create, pending or immediate, replaces the pending delete.

  • Scenario-3

    • Pending Action: Create

    • New Request: Delete

    • Result: The new delete, pending or immediate, replaces the pending create.

  • Scenario-4

    • Pending Action: Create

    • New Request: Create

    • Result: The new create is added to the pending create.

      Important

      Important: If the new create request is Apply Immediately - Yes, all creates are performed immediately. If the new create request is Apply Immediately - No, all creates are pending.

Arguments

CacheSecurityGroupName = ::StringRequired

The name of the cache security group to revoke ingress from.

EC2SecurityGroupName = ::StringRequired

The name of the Amazon EC2 security group to revoke access from.

EC2SecurityGroupOwnerId = ::StringRequired

The AWS account number of the Amazon EC2 security group owner. Note that this is not the same thing as an AWS access key ID - you must provide a valid AWS account number for this parameter.

Returns

RevokeCacheSecurityGroupIngressResult

Exceptions

CacheSecurityGroupNotFoundFault, AuthorizationNotFoundFault, InvalidCacheSecurityGroupStateFault, InvalidParameterValueException or InvalidParameterCombinationException.

TestFailover Operation

Represents the input of a TestFailover operation which test automatic failover on a specified node group (called shard in the console) in a replication group (called cluster in the console).

Note the following

  • A customer can use this operation to test automatic failover on up to 5 shards (called node groups in the ElastiCache API and AWS CLI) in any rolling 24-hour period.

  • If calling this operation on shards in different clusters (called replication groups in the API and CLI), the calls can be made concurrently.

  • If calling this operation multiple times on different shards in the same Redis (cluster mode enabled) replication group, the first node replacement must complete before a subsequent call can be made.

  • To determine whether the node replacement is complete you can check Events using the Amazon ElastiCache console, the AWS CLI, or the ElastiCache API. Look for the following automatic failover related events, listed here in order of occurrance:

    1. Replication group message: Test Failover API called for node group <node-group-id>

    2. Cache cluster message: Failover from master node <primary-node-id> to replica node <node-id> completed

    3. Replication group message: Failover from master node <primary-node-id> to replica node <node-id> completed

    4. Cache cluster message: Recovering cache nodes <node-id>

    5. Cache cluster message: Finished recovery for cache nodes <node-id>

Also see, Testing Multi-AZ with Automatic Failover in the ElastiCache User Guide.

Arguments

ReplicationGroupId = ::StringRequired

The name of the replication group (console: cluster) whose automatic failover is being tested by this operation.

NodeGroupId = ::StringRequired

The name of the node group (called shard in the console) in this replication group on which automatic failover is to be tested. You may test automatic failover on up to 5 node groups in any rolling 24-hour period.

Returns

TestFailoverResult

Exceptions

APICallRateForCustomerExceededFault, InvalidCacheClusterStateFault, InvalidReplicationGroupStateFault, NodeGroupNotFoundFault, ReplicationGroupNotFoundFault, TestFailoverNotAvailableFault, InvalidParameterValueException or InvalidParameterCombinationException.
