Instance Method Details
#add_tags_to_resource(params = {}) ⇒ Types::TagListMessage
A tag is a key-value pair where the key and value are case-sensitive. You can use tags to categorize and track all your ElastiCache resources, with the exception of global replication group. When you add or remove tags on replication groups, those actions will be replicated to all nodes in the replication group. For more information, see Resource-level permissions.
For example, you can use cost-allocation tags to your ElastiCache resources, Amazon 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.
Examples:
Example: AddTagsToResource
Example: AddTagsToResource
# Adds up to 10 tags, key/value pairs, to a cluster or snapshot resource.
resp = client.add_tags_to_resource({
resource_name: "arn:aws:elasticache:us-east-1:1234567890:cluster:my-mem-cluster",
tags: [
{
key: "APIVersion",
value: "20150202",
},
{
key: "Service",
value: "ElastiCache",
},
],
})
resp.to_h outputs the following:

#copy_snapshot(params = {}) ⇒ Types::CopySnapshotResult
Makes a copy of an existing snapshot.
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 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.

Options Hash (params):
-
:source_snapshot_name
(required, String)
—
The name of an existing snapshot from which to make a copy.
-
:target_snapshot_name
(required, String)
—

-
:target_bucket
(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.
-
:kms_key_id
(String)
—
The ID of the KMS key used to encrypt the target snapshot.
-
:tags
(Array<Types::Tag>)
—
A list of tags to be added to this resource. A tag is a key-value pair. A tag key must be accompanied by a tag value, although null is accepted.

Global Datastore for Redis OSS offers fully managed, fast, reliable and secure cross-region replication. Using Global Datastore for Redis OSS, you can create cross-region read replica clusters for ElastiCache (Redis OSS) to enable low-latency reads and disaster recovery across regions. For more information, see Replication Across Regions Using Global Datastore.
The GlobalReplicationGroupIdSuffix is the name of the Global datastore.
The PrimaryReplicationGroupId represents the name of the primary cluster that accepts writes and will replicate updates to the secondary cluster.

:global_replication_group_id_suffix
(required, String)
—
The suffix name of a Global datastore. Amazon ElastiCache automatically applies a prefix to the Global datastore ID when it is created. Each Amazon Region has its own prefix. For instance, a Global datastore ID created in the US-West-1 region will begin with "dsdfu" along with the suffix name you provide. The suffix, combined with the auto-generated prefix, guarantees uniqueness of the Global datastore name across multiple regions.
For a full list of Amazon Regions and their respective Global datastore iD prefixes, see Using the Amazon CLI with Global datastores .

#create_replication_group(params = {}) ⇒ Types::CreateReplicationGroupResult
Creates a Redis OSS (cluster mode disabled) or a Redis OSS (cluster mode enabled) replication group.
This API can be used to create a standalone regional replication group or a secondary replication group associated with a Global datastore.
A Redis OSS (cluster mode disabled) replication group is a collection of nodes, where one of the nodes is a read/write primary and the others are read-only replicas. Writes to the primary are asynchronously propagated to the replicas.
A Redis OSS cluster-mode enabled cluster is comprised of from 1 to 90 shards (API/CLI: node groups). Each shard has a primary node and up to 5 read-only replica nodes. The configuration can range from 90 shards and 0 replicas to 15 shards and 5 replicas, which is the maximum number or replicas allowed.
The node or shard limit can be increased to a maximum of 500 per cluster if the Redis OSS engine version is 5.0.6 or higher. For example, you can choose to configure a 500 node cluster that ranges between 83 shards (one primary and 5 replicas per shard) and 500 shards (single primary and no replicas). Make sure there are enough available IP addresses to accommodate the increase. Common pitfalls include the subnets in the subnet group have too small a CIDR range or the subnets are shared and heavily used by other clusters. For more information, see Creating a Subnet Group. For versions below 5.0.6, the limit is 250 per cluster.
To request a limit increase, see Amazon Service Limits and choose the limit type Nodes per cluster per instance type.
When a Redis OSS (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. If you need to increase or decrease the number of node groups (console: shards), you can use ElastiCache (Redis OSS) scaling. For more information, see Scaling ElastiCache (Redis OSS) Clusters in the ElastiCache User Guide.

params
(Hash)
(defaults to: {})
—
({})
Options Hash (params):
-
:replication_group_id
(required, String)
—
The replication group identifier. This parameter is stored as a lowercase string.
Constraints:
A name must contain from 1 to 40 alphanumeric characters or hyphens.
The first character must be a letter.
A name cannot end with a hyphen or contain two consecutive hyphens.
-
:replication_group_description
(required, String)
—
A user-created description for the replication group.
-
:global_replication_group_id
(String)
—
The name of the Global datastore
-
:primary_cluster_id
(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
, orReplicasPerNodeGroup
is specified. -
:automatic_failover_enabled
(Boolean)
—
Specifies whether a read-only replica is automatically promoted to read/write primary if the existing primary fails.
AutomaticFailoverEnabled
must be enabled for Redis OSS (cluster mode enabled) replication groups.Default: false
-
:multi_az_enabled
(Boolean)
—
A flag indicating if you have Multi-AZ enabled to enhance fault tolerance. For more information, see Minimizing Downtime: Multi-AZ.
-
:num_cache_clusters
(Integer)
—
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
istrue
, the value of this parameter must be at least 2. IfAutomaticFailoverEnabled
isfalse
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 (1 primary plus 5 replicas). -
:preferred_cache_cluster_a_zs
(Array<String>)
—
A list of EC2 Availability Zones in which the replication group's clusters are created. The order of the Availability Zones in the list is the order in which clusters are allocated. The primary cluster is created in the first AZ in the list.
This parameter is not used if there is more than one node group (shard). You should use
NodeGroupConfiguration
instead.If you are creating your replication group in an Amazon VPC (recommended), you can only locate clusters in Availability Zones associated with the subnets in the selected subnet group. The number of Availability Zones listed must equal the value of
NumCacheClusters
.Default: system chosen Availability Zones.
-
:num_node_groups
(Integer)
—
An optional parameter that specifies the number of node groups (shards) for this Redis OSS (cluster mode enabled) replication group. For Redis OSS (cluster mode disabled) either omit this parameter or set it to 1.
Default: 1
-
:replicas_per_node_group
(Integer)
—
An optional parameter that specifies the number of replica nodes in each node group (shard). Valid values are 0 to 5.
-
:node_group_configuration
(Array<Types::NodeGroupConfiguration>)
—
A list of node group (shard) configuration options. Each node group (shard) configuration has the following members:
PrimaryAvailabilityZone
,ReplicaAvailabilityZones
,ReplicaCount
, andSlots
.If you're creating a Redis OSS (cluster mode disabled) or a Redis OSS (cluster mode enabled) replication group, you can use this parameter to individually configure each node group (shard), or you can omit this parameter. However, it is required when seeding a Redis OSS (cluster mode enabled) cluster from a S3 rdb file. You must configure each node group (shard) using this parameter because you must specify the slots for each node group.
-
:cache_node_type
(String)
—
The compute and memory capacity of the nodes in the node group (shard).
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.

A setting that allows you to migrate your clients to use in-transit encryption, with no downtime.
When setting
TransitEncryptionEnabled
totrue
, you can set yourTransitEncryptionMode
topreferred
in the same request, to allow both encrypted and unencrypted connections at the same time. Once you migrate all your Redis OSS clients to use encrypted connections you can modify the value torequired
to allow encrypted connections only.Setting
TransitEncryptionMode
torequired
is a two-step process that requires you to first set theTransitEncryptionMode
topreferred
, after that you can setTransitEncryptionMode
torequired
.This process will not trigger the replacement of the replication group.
-
:cluster_mode
(String)
—
Enabled or Disabled. To modify cluster mode from Disabled to Enabled, you must first set the cluster mode to Compatible. Compatible mode allows your Redis OSS clients to connect using both cluster mode enabled and cluster mode disabled.

params
(Hash)
(defaults to: {})
—
({})
Options Hash (params):
-
:replication_group_id
(required, String)
—
The id of the replication group from which you want to remove replica nodes.
-
:new_replica_count
(Integer)
—
The number of read replica nodes you want at the completion of this operation. For Redis OSS (cluster mode disabled) replication groups, this is the number of replica nodes in the replication group. For Redis OSS (cluster mode enabled) replication groups, this is the number of replica nodes in each of the replication group's node groups.
The minimum number of replicas in a shard or replication group is:
Redis OSS (cluster mode disabled)
If Multi-AZ is enabled: 1
If Multi-AZ is not enabled: 0
Redis OSS (cluster mode enabled): 0 (though you will not be able to failover to a replica if your primary node fails)
-
:replica_configuration
(Array<Types::ConfigureShard>)
—
A list of
ConfigureShard
objects that can be used to configure each shard in a Redis OSS (cluster mode enabled) replication group. TheConfigureShard
has three members:NewReplicaCount
,NodeGroupId
, andPreferredAvailabilityZones
. -
:replicas_to_remove
(Array<String>)
—
A list of the node ids to remove from the replication group or node group (shard).
-
:apply_immediately
(required, Boolean)
—
If
True
, the number of replica nodes is decreased immediately.ApplyImmediately=False
is not currently supported.
Returns:
-
(Types::DecreaseReplicaCountResult)
—
Returns a response object which responds to the following methods:

#delete_cache_cluster(params = {}) ⇒ Types::DeleteCacheClusterResult
Deletes a previously provisioned cluster. DeleteCacheCluster
deletes
all associated cache nodes, node endpoints and the cluster itself.
When you receive a successful response from this operation, Amazon
ElastiCache immediately begins deleting the cluster; you cannot cancel
or revert this operation.
This operation is not valid for:
Redis OSS (cluster mode enabled) clusters
Redis OSS (cluster mode disabled) clusters
A cluster that is the last read replica of a replication group
A cluster that is the primary node of a replication group
A node group (shard) that has Multi-AZ mode enabled
A cluster from a Redis OSS (cluster mode enabled) replication group
A cluster that is not in the
available
state

#delete_global_replication_group(params = {}) ⇒ Types::DeleteGlobalReplicationGroupResult
Deleting a Global datastore is a two-step process:
First, you must DisassociateGlobalReplicationGroup to remove the secondary clusters in the Global datastore.
Once the Global datastore contains only the primary cluster, you can use the
DeleteGlobalReplicationGroup
API to delete the Global datastore while retainining the primary cluster usingRetainPrimaryReplicationGroup=true
.
Since the Global Datastore has only a primary cluster, you can delete
the Global Datastore while retaining the primary by setting
RetainPrimaryReplicationGroup=true
. The primary cluster is never
deleted when deleting a Global Datastore. It can only be deleted when
it no longer is associated with any Global Datastore.
When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the selected resources; you cannot cancel or revert this operation.

#delete_replication_group(params = {}) ⇒ Types::DeleteReplicationGroupResult
Deletes an existing replication group. By default, this operation
deletes the entire replication group, including the primary/primaries
and all of the read replicas. If the replication group has only one
primary, you can optionally delete only the read replicas, while
retaining the primary by setting RetainPrimaryCluster=true
.
When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the selected resources; you cannot cancel or revert this operation.
CreateSnapshot
permission is required to create a final snapshot.
Without this permission, the API call will fail with an Access
Denied
exception.
- This operation is valid for Redis OSS only.

#describe_cache_clusters(params = {}) ⇒ Types::CacheClusterMessage
Returns information about all provisioned clusters if no cluster identifier is specified, or about a specific cache cluster if a cluster identifier is supplied.
By default, abbreviated information about the clusters is returned. You can use the optional ShowCacheNodeInfo flag to retrieve detailed information about the cache nodes associated with the 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 is displayed until all of the nodes are successfully provisioned.
If the cluster is in the deleting state, only cluster-level information is displayed.
If cache nodes are currently being added to the cluster, node endpoint information and creation time for the additional nodes are not displayed until they are completely provisioned. When the cluster state is available, the cluster is ready for use.
If cache nodes are currently being removed from the cluster, no endpoint information for the removed nodes is displayed.
The returned response is a pageable response and is Enumerable. For details on usage see PageableResponse.
The following waiters are defined for this operation (see #wait_until for detailed usage):
- cache_cluster_available
- cache_cluster_deleted
Examples:
Example: DescribeCacheClusters
Example: DescribeCacheClusters
# Lists the details for up to 50 cache clusters.

Parameters:
-
params
(Hash)
(defaults to: {})
—
({})
Options Hash (params):
-
:cache_cluster_id
(String)
—
The user-supplied cluster identifier. If this parameter is specified, only information about that specific cluster is returned. This parameter isn't case sensitive.
-
:max_records
(Integer)
—
The maximum number of records to include in the response. If more records exist than the specified
MaxRecords
value, a marker is included in the response so that the remaining results can be retrieved.Default: 100
Constraints: minimum 20; maximum 100.
-
:marker
(String)
—
An optional marker returned from a prior request. Use this marker for pagination of results from this operation. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by
MaxRecords
. -
:show_cache_node_info
(Boolean)
—
An optional flag that can be included in the
DescribeCacheCluster
request to retrieve information about the individual cache nodes. -
:show_cache_clusters_not_in_replication_groups
(Boolean)
—
An optional flag that can be included in the
DescribeCacheCluster
request to show only nodes (API/CLI: clusters) that are not members of a replication group. In practice, this mean Memcached and single node Redis OSS clusters.
Returns:
-

#list_allowed_node_type_modifications(params = {}) ⇒ Types::AllowedNodeTypeModificationsMessage
Lists all available node types that you can scale your Redis OSS cluster's or replication group's current node type.
When you use the ModifyCacheCluster
or ModifyReplicationGroup
operations to scale your cluster or replication group, the value of
the CacheNodeType
parameter must be one of the node types returned
by this operation.
Examples:
Example: ListAllowedNodeTypeModifications
Example: ListAllowedNodeTypeModifications
# Lists all available node types that you can scale your Redis cluster's or replication group's current node type up to.
resp = client.list_allowed_node_type_modifications({

#list_tags_for_resource(params = {}) ⇒ Types::TagListMessage
Lists all tags currently on a named resource.
A tag is a key-value pair where the key and value are case-sensitive. You can use tags to categorize and track all your ElastiCache resources, with the exception of global replication group. When you add or remove tags on replication groups, those actions will be replicated to all nodes in the replication group. For more information, see Resource-level permissions.
If the cluster is not in the available state, ListTagsForResource
returns an error.
Examples:
Example: ListTagsForResource

Parameters:
-
params
(Hash)
(defaults to: {})
—
({})
Options Hash (params):
-
:cache_cluster_id
(required, String)
—
The cluster identifier. This value is stored as a lowercase string.
-
:num_cache_nodes
(Integer)
—
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 OSS, this value must be 1. For clusters running Memcached, this value must be between 1 and 40.
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 setNumCacheNodes
equal to the number of cache nodes currently in the cluster. -
:cache_node_ids_to_remove
(Array<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 ofNumCacheNodes
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. -
:az_mode
(String)
—
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.
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.
-
:new_availability_zones
(Array<String>)
—
This option is only supported on Memcached clusters. 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.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: 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.
-
:cache_security_group_names
(Array<String>)
—

You can use this parameter only with clusters that are created outside of an Amazon Virtual Private Cloud (Amazon VPC).
Constraints: Must contain no more than 255 alphanumeric characters. Must not be "Default".
-
:security_group_ids
(Array<String>)
—
Specifies the VPC Security Groups associated with the cluster.
This parameter can be used only with clusters that are created in an Amazon Virtual Private Cloud (Amazon VPC).

—
If
true
, this parameter causes the modifications in this request and any pending modifications to be applied, asynchronously and as soon as possible, regardless of thePreferredMaintenanceWindow
setting for the cluster.If
false
, changes to the cluster are applied on the next maintenance reboot, or the next failure reboot, whichever occurs first.If you perform a

—
The status of the Amazon SNS notification topic for the replication group. Notifications are sent only if the status is
active
.Valid values:
active
|inactive
-
:apply_immediately
(Boolean)
—
If
true
, this parameter causes the modifications in this request and any pending modifications to be applied, asynchronously and as soon as possible, regardless of thePreferredMaintenanceWindow
setting for the replication group.If
false
, changes to the nodes in the replication group are applied on the next maintenance reboot, or the next failure reboot, whichever occurs first.Valid values:
true
|false
Default:
false
-
:engine_version
(String)
—
The upgraded version of the cache engine to be run on the clusters in the replication group.
Important: You can upgrade to a newer engine version (see Selecting a Cache Engine and Version), but you cannot downgrade to an earlier engine version. If you want to use an earlier engine version, you must delete the existing replication group and create it anew with the earlier engine version.
-
:auto_minor_version_upgrade
(Boolean)
—
If you are running Redis OSS engine version 6.0 or later, set this parameter to yes if you want to opt-in to the next auto minor version upgrade campaign. This parameter is disabled for previous versions.
-
:snapshot_retention_limit
(Integer)
—
The number of days for which ElastiCache retains automatic node group (shard) snapshots before deleting them. For example, if you set
SnapshotRetentionLimit
to 5, a snapshot that was taken today is retained for 5 days before being deleted.Important If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off.
-
:snapshot_window
(String)
—
The daily time range (in UTC) during which ElastiCache begins taking a daily snapshot of the node group (shard) specified by
SnapshottingClusterId
.Example:
05:00-09:00
If you do not specify this parameter, ElastiCache automatically chooses an appropriate time range.
-
:cache_node_type
(String)
—
A valid cache node type that you want to scale this replication group to.
-
:auth_token
(String)
—
Reserved parameter. The password used to access a password protected server. This parameter must be specified with the
auth-token-update-strategy
parameter. Password constraints:Must be only printable ASCII characters
Must be at least 16 characters and no more than 128 characters in length

:auth_token_update_strategy
(String)
—
Specifies the strategy to use to update the AUTH token. This parameter must be specified with the
auth-token
parameter. Possible values:ROTATE - default, if no update strategy is provided
SET - allowed only after ROTATE
DELETE - allowed only when transitioning to RBAC
For more information, see Authenticating Users with Redis OSS AUTH
-
:user_group_ids_to_add
(Array<String>)
—
The ID of the user group you are associating with the replication group.
-
:user_group_ids_to_remove
(Array<String>)
—
The ID of the user group to disassociate from the replication group, meaning the users in the group no longer can access the replication group.
-

:transit_encryption_enabled
(Boolean)
—
A flag that enables in-transit encryption when set to true. If you are enabling in-transit encryption for an existing cluster, you must also set
TransitEncryptionMode
topreferred
. -
:transit_encryption_mode
(String)
—
A setting that allows you to migrate your clients to use in-transit encryption, with no downtime.
You must set
TransitEncryptionEnabled
totrue
, for your existing cluster, and setTransitEncryptionMode
topreferred
in the same request to allow both encrypted and unencrypted connections at the same time. Once you migrate all your Redis OSS clients to use encrypted connections you can set the value torequired
to allow encrypted connections only.Setting
TransitEncryptionMode
torequired
is a two-step process that requires you to first set theTransitEncryptionMode
topreferred
, after that you can setTransitEncryptionMode
torequired
. -
:cluster_mode
(String)
—
Enabled or Disabled. To modify cluster mode from Disabled to Enabled, you must first set the cluster mode to Compatible. Compatible mode allows your Redis OSS clients to connect using both cluster mode enabled and cluster mode disabled. After you migrate all Redis OSS clients to use cluster mode enabled, you can then complete cluster mode configuration and set the cluster mode to Enabled.
Returns:
-
(Types::ModifyReplicationGroupResult)
—
Returns a response object which responds to the following methods:
- #replication_group => Types::ReplicationGroup

#reboot_cache_cluster(params = {}) ⇒ Types::RebootCacheClusterResult
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 OSS (cluster mode disabled) clusters. Rebooting is not supported on Redis OSS (cluster mode enabled) clusters.
If you make changes to parameters that require a Redis OSS (cluster mode enabled) cluster reboot for the changes to be applied, see Rebooting a Cluster for an alternate process.
Examples:
Example: RebootCacheCluster
Example: RebootCacheCluster

#remove_tags_from_resource(params = {}) ⇒ Types::TagListMessage
Removes the tags identified by the TagKeys
list from the named
resource. A tag is a key-value pair where the key and value are
case-sensitive. You can use tags to categorize and track all your
ElastiCache resources, with the exception of global replication group.
When you add or remove tags on replication groups, those actions will
be replicated to all nodes in the replication group. For more
information, see Resource-level permissions.
Examples:
Example: RemoveTagsFromResource
Example: RemoveTagsFromResource
# Removes tags identified by a list of tag keys from the list of tags on the specified resource.
resp = client.remove_tags_from_resource({
resource_name: "arn:aws:elasticache:us-east-1:1234567890:cluster:my-mem-cluster",
tag_keys: [

#test_failover(params = {}) ⇒ Types::TestFailoverResult
Represents the input of a TestFailover
operation which tests
automatic failover on a specified node group (called shard in the
console) in a replication group (called cluster in the console).
This API is designed for testing the behavior of your application in case of ElastiCache failover. It is not designed to be an operational tool for initiating a failover to overcome a problem you may have with the cluster. Moreover, in certain conditions such as large-scale operational events, Amazon may block this API.
Note the following
A customer can use this operation to test automatic failover on up to 15 shards (called node groups in the ElastiCache API and Amazon 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 OSS (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 Amazon 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 primary node <primary-node-id> to replica node <node-id> completed
Replication group message:
Failover from primary 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

(required, String)
—
The ID of the replication group to which data is to be migrated.
-
:customer_node_endpoint_list
(required, Array<Types::CustomerNodeEndpoint>)
—
List of endpoints from which data should be migrated. List should have only one element.

#wait_until(waiter_name, params = {}, options = {}) {|w.waiter| ... } ⇒ Boolean
Polls an API operation until a resource enters a desired state.
Basic Usage
A waiter will call an API operation until:
- It is successful
- It enters a terminal state
- It makes the maximum number of attempts
In between attempts, the waiter will sleep.
# polls in a loop, sleeping between attempts
client.wait_until(waiter_name, params)
Configuration
You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You can pass configuration as the final arguments hash.
# poll for ~25 seconds
client.wait_until(waiter_name, params, {
max_attempts: 5,
delay: 5,
})
Callbacks
You can be notified before each polling attempt and before each
delay. If you throw :success
or :failure
from these callbacks,
it will terminate the waiter.
started_at = Time.now
client.wait_until(waiter_name, params, {
# disable max attempts
max_attempts: nil,
# poll for 1 hour, instead of a number of attempts
before_wait: -> (attempts, response) do
throw :failure if Time.now - started_at > 3600
end
})
Handling Errors
When a waiter is unsuccessful, it will raise an error. All of the failure errors extend from Waiters::Errors::WaiterFailed.
begin
client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
# resource did not enter the desired state in time
end
Valid Waiters
The following table lists the valid waiter names, the operations they call,
and the default :delay
and :max_attempts
values.
waiter_name | params | :delay | :max_attempts |
---|---|---|---|
cache_cluster_available | #describe_cache_clusters | 15 | 40 |
cache_cluster_deleted | #describe_cache_clusters | 15 | 40 |
replication_group_available | #describe_replication_groups | 15 | 40 |
replication_group_deleted | #describe_replication_groups | 15 | 40 |
Parameters:
- waiter_name (Symbol)
-
params
(Hash)

Options Hash (options):
- :max_attempts (Integer)
- :delay (Integer)
- :before_attempt (Proc)
- :before_wait (Proc)
Yields:
- (w.waiter)
Returns:
-
(Boolean)
—
Returns
true
if the waiter was successful.
Raises:
-
(Errors::FailureStateError)
—
Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.
-
(Errors::TooManyAttemptsError)
—
Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.
-
(Errors::UnexpectedError)
—
Raised when an error is encounted while polling for a resource that is not expected.
-
(Errors::NoSuchWaiterError)
—
Raised when you request to wait for an unknown state.
