fn add_tags_to_resource<'life0, 'async_trait>( &'life0 self, input: AddTagsToResourceMessage, ) -> Pin<Box<dyn Future<Output = Result<TagListMessage, RusotoError<AddTagsToResourceError>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

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.

fn authorize_cache_security_group_ingress<'life0, 'async_trait>( &'life0 self, input: AuthorizeCacheSecurityGroupIngressMessage, ) -> Pin<Box<dyn Future<Output = Result<AuthorizeCacheSecurityGroupIngressResult, RusotoError<AuthorizeCacheSecurityGroupIngressError>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

where Self: 'async_trait, 'life0: 'async_trait,

Makes a copy of an existing snapshot.

This operation is valid for Redis only.

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 for TargetSnapshotName.

where Self: 'async_trait, 'life0: 'async_trait,

Creates a new Amazon ElastiCache cache parameter group. An ElastiCache cache parameter group is a collection of parameters and their values that are applied to all of the nodes in any cluster or replication group using the CacheParameterGroup.

A newly created CacheParameterGroup is an exact duplicate of the default parameter group for the CacheParameterGroupFamily. To customize the newly created CacheParameterGroup you can change the values of specific parameters. For more information, see:

• ModifyCacheParameterGroup in the ElastiCache API Reference.

• Parameters and Parameter Groups in the ElastiCache User Guide.

fn create_global_replication_group<'life0, 'async_trait>( &'life0 self, input: CreateGlobalReplicationGroupMessage, ) -> Pin<Box<dyn Future<Output = Result<CreateGlobalReplicationGroupResult, RusotoError<CreateGlobalReplicationGroupError>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Global Datastore for Redis offers fully managed, fast, reliable and secure cross-region replication. Using Global Datastore for Redis, you can create cross-region read replica clusters for ElastiCache for Redis 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.

fn create_replication_group<'life0, 'async_trait>( &'life0 self, input: CreateReplicationGroupMessage, ) -> Pin<Box<dyn Future<Output = Result<CreateReplicationGroupResult, RusotoError<CreateReplicationGroupError>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

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) replication group is a collection of 1 to 90 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. 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.

This operation is valid for Redis only.

where Self: 'async_trait, 'life0: 'async_trait,

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 DeleteGlobalReplicationGroup API to delete the Global Datastore while retainining the primary cluster using Retain…= true.

Since the Global Datastore has only a primary cluster, you can delete the Global Datastore 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.

fn delete_replication_group<'life0, 'async_trait>( &'life0 self, input: DeleteReplicationGroupMessage, ) -> Pin<Box<dyn Future<Output = Result<DeleteReplicationGroupResult, RusotoError<DeleteReplicationGroupError>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

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.

This operation is valid for Redis only.

where Self: 'async_trait, 'life0: 'async_trait,

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.

fn remove_tags_from_resource<'life0, 'async_trait>( &'life0 self, input: RemoveTagsFromResourceMessage, ) -> Pin<Box<dyn Future<Output = Result<TagListMessage, RusotoError<RemoveTagsFromResourceError>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Removes the tags identified by the TagKeys list from the named resource.

fn reset_cache_parameter_group<'life0, 'async_trait>( &'life0 self, input: ResetCacheParameterGroupMessage, ) -> Pin<Box<dyn Future<Output = Result<CacheParameterGroupNameMessage, RusotoError<ResetCacheParameterGroupError>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

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.

fn revoke_cache_security_group_ingress<'life0, 'async_trait>( &'life0 self, input: RevokeCacheSecurityGroupIngressMessage, ) -> Pin<Box<dyn Future<Output = Result<RevokeCacheSecurityGroupIngressResult, RusotoError<RevokeCacheSecurityGroupIngressError>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Revokes ingress from a cache security group. Use this operation to disallow access from an Amazon EC2 security group that had been previously authorized.

fn start_migration<'life0, 'async_trait>( &'life0 self, input: StartMigrationMessage, ) -> Pin<Box<dyn Future<Output = Result<StartMigrationResponse, RusotoError<StartMigrationError>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Start the migration of data.

fn test_failover<'life0, 'async_trait>( &'life0 self, input: TestFailoverMessage, ) -> Pin<Box<dyn Future<Output = Result<TestFailoverResult, RusotoError<TestFailoverError>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

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:

  1. Replication group message: Test Failover API called for node group <node-group-id>

  2. Cache cluster message: Failover from master node <primary-node-id> to replica node <node-id> completed

  3. Replication group message: Failover from master 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>
