{'ReplicationGroup': {'Engine': 'string'}}
Creates a Valkey or Redis OSS (cluster mode disabled) or a Valkey or 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 Valkey or 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 Valkey or 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 Valkey or 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 Valkey or 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 scaling. For more information, see Scaling self-designed clusters in the ElastiCache User Guide.

string
[REQUIRED]
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.
string
[REQUIRED]
A user-created description for the replication group.
string
The name of the Global datastore
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.
boolean
Specifies whether a read-only replica is automatically promoted to read/write primary if the existing primary fails.
AutomaticFailoverEnabled must be enabled for Valkey or Redis OSS (cluster mode enabled) replication groups.
Default: false
boolean
A flag indicating if you have Multi-AZ enabled to enhance fault tolerance. For more information, see Minimizing Downtime: Multi-AZ.
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 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).
list
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.
Default: system chosen Availability Zones.
(string) --
integer
An optional parameter that specifies the number of node groups (shards) for this Valkey or Redis OSS (cluster mode enabled) replication group. For Valkey or Redis OSS (cluster mode disabled) either omit this parameter or set it to 1.

If you're creating a Valkey or Redis OSS (cluster mode disabled) or a Valkey or 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 Valkey or 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.

boolean
Enables data tiering. Data tiering is only supported for replication groups using the r6gd node type. This parameter must be set to true when using r6gd nodes. For more information, see Data tiering.
string
Must be either ipv4 | ipv6 | dual_stack. IPv6 is supported for workloads using Valkey 7.2 and above, Redis OSS engine version 6.2 and above or Memcached engine version 1.6.6 and above on all instances built on the Nitro system.
string
The network type you choose when creating a replication group, either ipv4 | ipv6. IPv6 is supported for workloads using Valkey 7.2 and above, Redis OSS engine version 6.2 and above or Memcached engine version 1.6.6 and above on all instances built on the Nitro system.
string
A setting that allows you to migrate your clients to use in-transit encryption, with no downtime.
When setting TransitEncryptionEnabled to true, you can set your TransitEncryptionMode to preferred in the same request, to allow both encrypted and unencrypted connections at the same time. Once you migrate all your Valkey or Redis OSS clients to use encrypted connections you can modify 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, after that you can set TransitEncryptionMode to required.
This process will not trigger the replacement of the replication group.
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 Valkey or Redis OSS clients to connect using both cluster mode enabled and cluster mode disabled. After you migrate all Valkey or Redis OSS clients to use cluster mode enabled, you can then complete cluster mode configuration and set the cluster mode to Enabled.
string
The name of the snapshot used to create a replication group. Available for Valkey, Redis OSS only.

{'ReplicationGroup': {'Engine': 'string'}}
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.

[REQUIRED]
The identifier for the cluster to be deleted. This parameter is not case sensitive.
boolean
If set to true, all of the read replicas are deleted, but the primary node is retained.
string
The name of a final node group (shard) snapshot. ElastiCache creates the snapshot from the primary node in the cluster, rather than one of the replicas; this is to ensure that it captures the freshest data. After the final snapshot is taken, the replication group is immediately deleted.

[REQUIRED]
The cluster identifier. This value is stored as a lowercase string.
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 Valkey or Redis OSS, this value must be 1. For clusters running Memcached, this value must be between 1 and 40.
list
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.
(string) --
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.
list
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

string
The network type you choose when modifying a cluster, either ipv4 | ipv6. IPv6 is supported for workloads using Valkey 7.2 and above, Redis OSS engine version 6.2 and above or Memcached engine version 1.6.6 and above on all instances built on the Nitro system.
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 to preferred.
string
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 Valkey or Redis OSS 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, after that you can set TransitEncryptionMode to required.
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 Valkey or Redis OSS clients to connect using both cluster mode enabled and cluster mode disabled. After you migrate all Valkey or Redis OSS clients to use cluster mode enabled, you can then complete cluster mode configuration and set the cluster mode to Enabled.

{'ReplicationGroup': {'Engine': 'string'}}
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 Valkey or 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:
