ElastiCache.Client¶A low-level client representing 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.

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 .

Constraints:
The ID of the replication group to which this cluster should belong. If this parameter is specified, the cluster is added to the specified replication group as a read replica; otherwise, the cluster is a standalone primary that is not part of any replication group.
If the specified replication group is Multi-AZ enabled and the Availability Zone is not specified, the cluster is created in Availability Zones that provide the best spread of read replicas across Availability Zones.
Note
This parameter is only valid if the Engine parameter is redis .
Specifies whether the nodes in this Memcached cluster are created in a single Availability Zone or created across multiple Availability Zones in the cluster's region.
This parameter is only supported for Memcached clusters.
If the AZMode and PreferredAvailabilityZones are not specified, ElastiCache assumes single-az mode.

This API can be used to create a standalone regional replication group or a secondary replication group associated with a Global datastore.
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 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 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 (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 avail yourself of ElastiCache for Redis' scaling. For more information, see Scaling ElastiCache for Redis Clusters in the ElastiCache User Guide .
Note
This operation is valid for Redis only.

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.
Specifies whether a read-only replica is automatically promoted to read/write primary if the existing primary fails.
AutomaticFailoverEnabledmust be enabled for Redis (cluster mode enabled) replication groups.
Default: false
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 (1 primary plus 5 replicas).
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.
Note
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.
An optional parameter that specifies the number of node groups (shards) for this Redis (cluster mode enabled) replication group. For Redis (cluster mode disabled) either omit this parameter or set it to 1.
Default: 1
A list of node group (shard) configuration options. Each node group (shard) configuration has the following members: PrimaryAvailabilityZone , ReplicaAvailabilityZones , ReplicaCount , and Slots .
If you're creating a Redis (cluster mode disabled) or a Redis (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 (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.
Node group (shard) configuration options. Each node group (shard) configuration has the following: Slots , PrimaryAvailabilityZone , ReplicaAvailabilityZones , ReplicaCount .
Either the ElastiCache for Redis supplied 4-digit id or a user supplied id for the node group these configuration values apply to.
A string that specifies the keyspace for a particular node group. Keyspaces range from 0 to 16,383. The string is in the format startkey-endkey .
Example: "0-3999"
The number of read replica nodes in this node group (shard).

[REQUIRED]
The cluster identifier. This value is stored as a lowercase string.
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 40.
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.
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.
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.
Note
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:
NumCacheNodes=5 (3 + 2) and optionally specify two Availability Zones for the two new nodes.NumCacheNodes=6 ((3 + 2) + 1) and optionally specify an Availability Zone for the new node.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
Warning
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.
A list of cache security group names to authorize on this cluster. This change is asynchronously applied as soon as possible.
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".
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).
Specifies the weekly time range during which maintenance on the cluster is performed. It is specified as a range in the format ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window is a 60 minute period.
Valid values for ddd are:
sunmontuewedthufrisatExample: sun:23:00-mon:01:30
The Amazon Resource Name (ARN) of the Amazon SNS topic to which notifications are sent.
Note
The Amazon SNS topic owner must be same as the cluster owner.
ApplyImmediately parameter is specified as true for this request.The status of the Amazon SNS notification topic. Notifications are sent only if the status is active .
Valid values: active | inactive
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 the PreferredMaintenanceWindow 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.
Warning
If you perform a ModifyCacheCluster before a pending modification is applied, the pending modification is replaced by the newer modification.
Valid values: true | false
Default: false
The upgraded version of the cache engine to be run on the cache nodes.
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 cluster and create it anew with the earlier engine version.
The number of days for which ElastiCache retains automatic cluster 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.
Note
If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off.
Reserved parameter. The password used to access a password protected server. This parameter must be specified with the auth-token-update parameter. Password constraints:

Default: false
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.
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.
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.
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:

Specify if log delivery is enabled. Default true .
ipv4 | ipv6 . IPv6 is supported for workloads using Redis engine version 6.2 onward or Memcached engine version 1.6.6 on all instances built on the Nitro system.TransitEncryptionMode to preferred .A setting that allows you to migrate your clients to use in-transit encryption, with no downtime.
You must set TransitEncryptionEnabled to true , for your existing cluster, and set TransitEncryptionMode to preferred in the same request to allow both encrypted and unencrypted connections at the same time. Once you migrate all your Redis clients to use encrypted connections you can set the value to required to allow encrypted connections only.
Setting TransitEncryptionMode to required is a two-step process that requires you to first set the TransitEncryptionMode to preferred first, after that you can set TransitEncryptionMode to required .

ElastiCache.Client.exceptions.GlobalReplicationGroupNotFoundFaultElastiCache.Client.exceptions.InvalidGlobalReplicationGroupStateFaultElastiCache.Client.exceptions.InvalidParameterValueExceptionreboot_cache_cluster(**kwargs)¶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.
