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.

elasticache([::AWSConfig], "AddTagsToResource", ResourceName=, Tags=)
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 = ::String
– Required
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

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 theCopySnapshot
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 forTargetSnapshotName
.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 = ::String
– Required
The name of an existing snapshot from which to make a copy.
TargetSnapshotName = ::String
– Required
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.

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 = ::String
– Required
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 = ::String
– Required
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, ...]

Engine = ::String
The name of the cache engine to be used for the clusters in this replication group.
EngineVersion = ::String
The version number of the cache engine to be used for the clusters in this replication group. To view the supported cache engine versions, use the DescribeCacheEngineVersions
operation.
Important: You can upgrade to a newer engine version (see Selecting a Cache Engine and Version) in the ElastiCache User Guide, but you cannot downgrade to an earlier engine version. If you want to use an earlier engine version, you must delete the existing cluster or replication group and create it anew with the earlier engine version.

If you are running Redis version 3.2.4 or later, only one node group (shard), and want to use a default parameter group, we recommend that you specify the parameter group by name.
To create a Redis (cluster mode disabled) replication group, use
CacheParameterGroupName=default.redis3.2
.To create a Redis (cluster mode enabled) replication group, use
CacheParameterGroupName=default.redis3.2.cluster.on
.
CacheSubnetGroupName = ::String

SnapshotWindow = ::String
The daily time range (in UTC) during which ElastiCache begins taking a daily snapshot of your node group (shard).
Example: 05:00-09:00
If you do not specify this parameter, ElastiCache automatically chooses an appropriate time range.
AuthToken = ::String
Reserved parameter. The password used to access a password protected server.
This parameter is valid only if:

using AWSCore.Services.elasticache
elasticache([::AWSConfig], "ModifyCacheCluster", arguments::Dict)
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 = ::String
– Required
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. Ifcross-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

using AWSCore.Services.elasticache
elasticache([::AWSConfig], "RebootCacheCluster", arguments::Dict)
elasticache([::AWSConfig], "RebootCacheCluster", CacheClusterId=, CacheNodeIdsToReboot=)
RebootCacheCluster Operation
Reboots some, or all, of the cache nodes within a provisioned cluster. This operation applies any modified cache parameter groups to the cluster. The reboot operation takes place as soon as possible, and results in a momentary outage to the cluster. During the reboot, the cluster status is set to REBOOTING.
The reboot causes the contents of the cache (for each cache node being rebooted) to be lost.
When the reboot is complete, a cluster event is created.
Rebooting a cluster is currently supported on Memcached and Redis (cluster mode disabled) clusters. Rebooting is not supported on Redis (cluster mode enabled) clusters.
If you make changes to parameters that require a Redis (cluster mode enabled) cluster reboot for the changes to be applied, see Rebooting a Cluster for an alternate process.
Arguments
CacheClusterId = ::String
– Required
The cluster identifier. This parameter is stored as a lowercase string.
CacheNodeIdsToReboot = [::String, ...]
– Required
A list of cache node IDs to reboot. A node ID is a numeric identifier (0001, 0002, etc.). To reboot an entire cluster, specify all of the cache node IDs.
Returns
RebootCacheClusterResult
Exceptions
InvalidCacheClusterStateFault
or CacheClusterNotFoundFault

elasticache([::AWSConfig], "ResetCacheParameterGroup", CacheParameterGroupName=, <keyword arguments>)
ResetCacheParameterGroup Operation
Modifies the parameters of a cache parameter group to the engine or system default value. You can reset specific parameters by submitting a list of parameter names. To reset the entire cache parameter group, specify the ResetAllParameters
and CacheParameterGroupName
parameters.
Arguments
CacheParameterGroupName = ::String
– Required
The name of the cache parameter group to reset.
ResetAllParameters = ::Bool
If true
, all parameters in the cache parameter group are reset to their default values. If false
, only the parameters listed by ParameterNameValues
are reset to their default values.
Valid values: true
| false
ParameterNameValues = [[ ... ], ...]
An array of parameter names to reset to their default values. If ResetAllParameters
is true
, do not use ParameterNameValues
. If ResetAllParameters
is false
, you must specify the name of at least one parameter to reset.
ParameterNameValues = [[
"ParameterName" => ::String,
"ParameterValue" => ::String
], ...]
Returns
CacheParameterGroupNameMessage
Exceptions
InvalidCacheParameterGroupStateFault
, CacheParameterGroupNotFoundFault

AWSSDK.ElastiCache.test_failover
— Function.using AWSSDK.ElastiCache.test_failover

test_failover([::AWSConfig]; ReplicationGroupId=, NodeGroupId=)
using AWSCore.Services.elasticache
elasticache([::AWSConfig], "TestFailover", arguments::Dict)
elasticache([::AWSConfig], "TestFailover", ReplicationGroupId=, NodeGroupId=)
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:
Replication group message:
Test Failover API called for node group <node-group-id>
Cache cluster message:
Failover from master node <primary-node-id> to replica node <node-id> completed
Replication group message:
Failover from master node <primary-node-id> to replica node <node-id> completed
Cache cluster message:
Recovering cache nodes <node-id>
Cache cluster message:
Finished recovery for cache nodes <node-id>
For more information see:
Viewing ElastiCache Events in the ElastiCache User Guide
DescribeEvents in the ElastiCache API Reference
Also see, Testing Multi-AZ with Automatic Failover in the ElastiCache User Guide.
Arguments
ReplicationGroupId = ::String
– Required
The name of the replication group (console: cluster) whose automatic failover is being tested by this operation.
NodeGroupId = ::String
– Required
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
