DESCRIPTION

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.

For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/elasticache-2015-02-02

METHODS

AddTagsToResource

ResourceName => Str
Tags => ArrayRef[Paws::ElastiCache::Tag]

Each argument is described in detail in: Paws::ElastiCache::AddTagsToResource

Returns: a Paws::ElastiCache::TagListMessage instance

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 (http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Tagging.html) in the ElastiCache User Guide.

AuthorizeCacheSecurityGroupIngress

CacheSecurityGroupName => Str
EC2SecurityGroupName => Str
EC2SecurityGroupOwnerId => Str

Each argument is described in detail in: Paws::ElastiCache::AuthorizeCacheSecurityGroupIngress

Returns: a Paws::ElastiCache::AuthorizeCacheSecurityGroupIngressResult instance

Allows network ingress to a cache security group. Applications using ElastiCache must be running on Amazon EC2, and Amazon EC2 security groups are used as the authorization mechanism.

You cannot authorize ingress from an Amazon EC2 security group in one region to an ElastiCache cluster in another region.

CopySnapshot

SourceSnapshotName => Str
TargetSnapshotName => Str
[TargetBucket => Str]

Each argument is described in detail in: Paws::ElastiCache::CopySnapshot

Returns: a Paws::ElastiCache::CopySnapshotResult instance

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 (http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Snapshots.Exporting.html) and Authentication & Access Control (http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/IAM.html).

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 (http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Snapshots.Exporting.html#Snapshots.Exporting.CreateBucket) 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 (http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Snapshots.Exporting.html#Snapshots.Exporting.CreateBucket) 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 (http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Snapshots.Exporting.html#Snapshots.Exporting.CreateBucket) 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.
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 (http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Snapshots.Exporting.html#Snapshots.Exporting.GrantAccess) 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 (http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Snapshots.Exporting.html#Snapshots.Exporting.GrantAccess) 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 (http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Snapshots.Exporting.html#Snapshots.Exporting.GrantAccess) in the ElastiCache User Guide.

Each argument is described in detail in: Paws::ElastiCache::CreateReplicationGroup

Returns: a Paws::ElastiCache::CreateReplicationGroupResult instance

Creates a Redis (cluster mode disabled) or a Redis (cluster mode enabled) replication group.

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 15 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. You cannot alter a Redis (cluster mode enabled) replication group after it has been created. However, if you need to increase or decrease the number of node groups (console: shards), you can avail yourself of ElastiCache for Redis' enhanced backup and restore. For more information, see Restoring From a Backup with Cluster Resizing (http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/backups-restoring.html) in the ElastiCache User Guide.

TestFailover

NodeGroupId => Str
ReplicationGroupId => Str

Each argument is described in detail in: Paws::ElastiCache::TestFailover

Returns: a Paws::ElastiCache::TestFailoverResult instance

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>
