Client

class ElastiCache.Client

A low-level client representing Amazon ElastiCache:

client = session.create_client('elasticache')

These are the available methods:

add_tags_to_resource(**kwargs)

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 .

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
copy_snapshot(**kwargs)

Makes a copy of an existing snapshot.

Note

This operation is valid for Redis only.

Warning

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 .
  • 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 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 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 in the ElastiCache User Guide.

Request Syntax

response = client.copy_snapshot(
    SourceSnapshotName='string',
    TargetSnapshotName='string',
    TargetBucket='string'
)
Parameters
  • SourceSnapshotName (string) --

    [REQUIRED]

    The name of an existing snapshot from which to make a copy.

  • TargetSnapshotName (string) --

    [REQUIRED]

    A name for the snapshot copy. ElastiCache does not permit overwriting a snapshot, therefore this name must be unique within its context - ElastiCache or an Amazon S3 bucket if exporting.

  • TargetBucket (string) --

    The Amazon S3 bucket to which the snapshot is exported. This parameter is used only when exporting a snapshot for external access.

    When using this parameter to export a snapshot, be sure Amazon ElastiCache has the needed permissions to this S3 bucket. For more information, see Step 2: Grant ElastiCache Access to Your Amazon S3 Bucket in the Amazon ElastiCache User Guide .

    Due to current limitations on Redis (cluster mode disabled), this operation or parameter is not supported on Redis (cluster mode enabled) replication groups.

    The ID of the replication group to which this cache cluster should belong. If this parameter is specified, the cache cluster is added to the specified replication group as a read replica; otherwise, the cache 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 cache 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 .

  • AZMode (string) --

    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 cache clusters.

    If the AZMode and PreferredAvailabilityZones are not specified, ElastiCache assumes single-az mode.

  • PreferredAvailabilityZone (string) --

    The EC2 Availability Zone in which the cache cluster is created.

    All nodes belonging to this Memcached cache cluster are placed in the preferred Availability Zone. If you want to create your nodes across multiple Availability Zones, use PreferredAvailabilityZones .

  • PreferredAvailabilityZones (list) --

    A list of the Availability Zones in which cache nodes are created. The order of the zones in the list is not important.

    This option is only supported on Memcached.

    Note

    If you are creating your cache cluster in an Amazon VPC (recommended) you can only locate nodes in Availability Zones that are associated with the subnets in the selected subnet group.

    The number of Availability Zones listed must equal the value of NumCacheNodes .

    If you want all the nodes in the same Availability Zone, use PreferredAvailabilityZone instead, or repeat the Availability Zone multiple times in the list.

    Default: System chosen Availability Zones.

    • (string) --
  • NumCacheNodes (integer) --

    The initial number of cache nodes that the cache cluster has.

    For clusters running Redis, this value must be 1. For clusters running Memcached, this value must be between 1 and 20.

            The unique identifier for the subnet.

          • SubnetAvailabilityZone (dict) --

create_replication_group(**kwargs)

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 cache clusters, where one of the cache 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 in the ElastiCache User Guide .

Note

This operation is valid for Redis only.

delete_cache_cluster(**kwargs)

Deletes a previously provisioned cache cluster. DeleteCacheCluster deletes all associated cache nodes, node endpoints and the cache cluster itself. When you receive a successful response from this operation, Amazon ElastiCache immediately begins deleting the cache cluster; you cannot cancel or revert this operation.

This operation cannot be used to delete a cache cluster that is the last read replica of a replication group or node group (shard) that has Multi-AZ mode enabled or a cache cluster from a Redis (cluster mode enabled) replication group.

Warning

Due to current limitations on Redis (cluster mode disabled), this operation or parameter is not supported on Redis (cluster mode enabled) replication groups.

describe_cache_clusters(**kwargs)

Returns information about all provisioned cache clusters if no cache cluster identifier is specified, or about a specific cache cluster if a cache cluster identifier is supplied.

By default, abbreviated information about the cache clusters is returned. You can use the optional ShowCacheNodeInfo flag to retrieve detailed information about the cache nodes associated with the cache clusters. These details include the DNS address and port for the cache node endpoint.

If the cluster is in the creating state, only cluster-level information is displayed until all of the nodes are successfully provisioned.

If the cluster is in the deleting state, only cluster-level information is displayed.

If cache nodes are currently being added to the cache cluster, node endpoint information and creation time for the additional nodes are not displayed until they are completely provisioned. When the cache cluster state is available , the cluster is ready for use.

If cache nodes are currently being removed from the cache cluster, no endpoint information for the removed nodes is displayed.

  • CacheClusterId (string) -- The user-supplied cluster identifier. If this parameter is specified, only information about that specific cache cluster is returned. This parameter isn't case sensitive.
  • MaxRecords (integer) --

    The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a marker is included in the response so that the remaining results can be retrieved.

    Default: 100

    Constraints: minimum 20; maximum 100.

  • Marker (string) -- An optional marker returned from a prior request. Use this marker for pagination of results from this operation. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords .
  • ShowCacheNodeInfo (boolean) -- An optional flag that can be included in the DescribeCacheCluster request to retrieve information about the individual cache nodes.
  • ShowCacheClustersNotInReplicationGroups (boolean) -- An optional flag that can be included in the DescribeCacheCluster request to show only nodes (API/CLI: clusters) that are not members of a replication group. In practice, this mean Memcached and single node Redis clusters.

Request Syntax

response = client.modify_cache_cluster(
    CacheClusterId='string',
    NumCacheNodes=123,
    CacheNodeIdsToRemove=[
        'string',
    ],
    AZMode='single-az'|'cross-az',
    NewAvailabilityZones=[
        'string',
    ],
    CacheSecurityGroupNames=[
        'string',

    CacheParameterGroupName='string',
    NotificationTopicStatus='string',
    ApplyImmediately=True|False,
    EngineVersion='string',
    AutoMinorVersionUpgrade=True|False,
    SnapshotRetentionLimit=123,
    SnapshotWindow='string',
    CacheNodeType='string'
)
Parameters
  • CacheClusterId (string) --

    [REQUIRED]

    The cache cluster identifier. This value is stored as a lowercase string.

  • NumCacheNodes (integer) --

    The number of cache nodes that the cache 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 20.

    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 cache cluster.

  • CacheNodeIdsToRemove (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 ModifyCacheCluser call is 5, you must list 2 (7 - 5) cache node IDs to remove.

    • (string) --
  • AZMode (string) --

    Specifies whether the new nodes in this Memcached cache 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 cache clusters.

    Note

    You cannot specify single-az if the Memcached cache 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. For instructions on how to move existing Memcached nodes to different Availability Zones, see the Availability Zone Considerations section of Cache Node Considerations for Memcached .

  • NewAvailabilityZones (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.

    This option is only supported on Memcached clusters.

    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
      • Pending Action: Create
      • New Request: Delete
      • Result: The new delete, pending or immediate, replaces the pending create.
    • Scenario-4
      • Pending Action: Create
      • New Request: Create
      • Result: The new create is added to the pending create.

      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.

    • (string) --
  • CacheSecurityGroupNames (list) --

    Valid values for ddd are:

    • sun
    • mon
    • tue
    • wed
    • thu
    • fri
    • sat

    Example: sun:23:00-mon:01:30

  • NotificationTopicArn (string) --

  • NotificationTopicStatus (string) --

    The status of the Amazon SNS notification topic. Notifications are sent only if the status is active .

    Valid values: active | inactive

  • ApplyImmediately (boolean) --

    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 cache cluster.

    If false , changes to the cache 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

  • EngineVersion (string) --

    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 cache cluster and create it anew with the earlier engine version.
  • AutoMinorVersionUpgrade (boolean) -- This parameter is currently disabled.
  • SnapshotRetentionLimit (integer) --

    The number of days for which ElastiCache retains automatic cache 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.

  • SnapshotWindow (string) -- The daily time range (in UTC) during which ElastiCache begins taking a daily snapshot of your cache cluster.

reboot_cache_cluster(**kwargs)

Reboots some, or all, of the cache nodes within a provisioned cache cluster. This operation applies any modified cache parameter groups to the cache cluster. The reboot operation takes place as soon as possible, and results in a momentary outage to the cache cluster. During the reboot, the cache 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 cache cluster event is created.

test_failover(**kwargs)

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:
    • Replication group message: Test Failover API called for node group node-group-id
    • Cache cluster message: Failover from master node primary-node-idto replica node node-idcompleted
    • Replication group message: Failover from master node primary-node-idto replica node node-idcompleted
    • Cache cluster message: Recovering cache nodes node-id
    • Cache cluster message: Finished recovery for cache nodes node-id

For more information see:

Also see, Testing Multi-AZ with Automatic Failover in the ElastiCache User Guide .

Waiters

The available waiters are:

class ElastiCache.Waiter.CacheClusterAvailable
waiter = client.get_waiter('cache_cluster_available')
wait(**kwargs)

Polls ElastiCache.Client.describe_cache_clusters() every 30 seconds until a successful state is reached. An error is returned after 60 failed checks.

See also: AWS API Documentation

Request Syntax

waiter.wait(
    CacheClusterId='string',
    MaxRecords=123,
    Marker='string',
    ShowCacheNodeInfo=True|False,
    ShowCacheClustersNotInReplicationGroups=True|False
)
Parameters
  • CacheClusterId (string) -- The user-supplied cluster identifier. If this parameter is specified, only information about that specific cache cluster is returned. This parameter isn't case sensitive.
  • MaxRecords (integer) --

    The maximum number of records to include in the response. If more records exist than the specified MaxRecords value, a marker is included in the response so that the remaining results can be retrieved.

    Default: 100

    Constraints: minimum 20; maximum 100.

  • Marker (string) -- An optional marker returned from a prior request. Use this marker for pagination of results from this operation. If this parameter is specified, the response includes only records beyond the marker, up to the value specified by MaxRecords .
  • ShowCacheNodeInfo (boolean) -- An optional flag that can be included in the DescribeCacheCluster request to retrieve information about the individual cache nodes.
  • ShowCacheClustersNotInReplicationGroups (boolean) -- An optional flag that can be included in the DescribeCacheCluster request to show only nodes (API/CLI: clusters) that are not members of a replication group. In practice, this mean Memcached and single node Redis clusters.
Returns

None

class ElastiCache.Waiter.CacheClusterDeleted
waiter = client.get_waiter('cache_cluster_deleted')
wait(**kwargs)

Polls ElastiCache.Client.describe_cache_clusters() every 30 seconds until a successful state is reached. An error is returned after 60 failed checks.
