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.

actionAddTagsToResource.getAddTagsToResource

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 .

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 in the ElastiCache User Guide.

actionCreateReplicationGroup.getCreateReplicationGroup

Creates a Redis (cluster mode disabled) or a Redis (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 (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 . For versions below 5.0.6, the limit is 250 per cluster.

To request a limit increase, see 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 in the ElastiCache User Guide.

This operation is valid for Redis only.

actionRebalanceSlotsInGlobalReplicationGroup.getRebalanceSlotsInGlobalReplicationGroup

Redistribute slots to ensure uniform distribution across existing shards in the cluster.
actionRebalanceSlotsInGlobalReplicationGroup.postRebalanceSlotsInGlobalReplicationGroup

Redistribute slots to ensure uniform distribution across existing shards in the cluster.
actionRebootCacheCluster.getRebootCacheCluster

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 for an alternate process.
actionRebootCacheCluster.postRebootCacheCluster

actionRemoveTagsFromResource.getRemoveTagsFromResource

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 .
actionRemoveTagsFromResource.postRemoveTagsFromResource

actionTestFailover.getTestFailover
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).

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 5 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 (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:
  1. Replication group message: Test Failover API called for node group <node-group-id>
  2. Cache cluster message: Failover from primary node <primary-node-id> to replica node <node-id> completed
  3. Replication group message: Failover from primary 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>
  For more information see:
