Amazon MemoryDB

2022/11/03 - Amazon MemoryDB - 10 updated api methods

Changes  Adding support for r6gd instances for MemoryDB Redis with data tiering. In a cluster with data tiering enabled, when available memory capacity is exhausted, the least recently used data is automatically tiered to solid state drives for cost-effective capacity scaling with minimal performance impact.

param SourceSnapshotName

[REQUIRED]

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

type TargetBucket

string

param TargetBucket

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 MemoryDB has the needed permissions to this S3 bucket. For more information, see Step 2: Grant MemoryDB Access to Your Amazon S3 Bucket.

A list of tags to be added to this resource. A tag is a key-value pair. A tag key must be accompanied by a tag value, although null is accepted.

  • (dict) --

    A tag that can be added to an MemoryDB resource. Tags are composed of a Key/Value pair. You can use tags to categorize and track all your MemoryDB resources. When you add or remove tags on clusters, those actions will be replicated to all nodes in the cluster. A tag with a null Value is permitted. For more information, see Tagging your MemoryDB resources

    • Key (string) --

      The key for the tag. May not be null.

FailoverShard (updated) Link ¶

{'Cluster': {'DataTiering': 'true | false'}}

Used to failover a shard. This API is designed for testing the behavior of your application in case of MemoryDB failover. It is not designed to be used as a production-level 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.

string

param SnapshotWindow

The daily time range (in UTC) during which MemoryDB begins taking a daily snapshot of your cluster.

type SnapshotRetentionLimit

integer

param SnapshotRetentionLimit

The number of days for which MemoryDB retains automatic 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.

type NodeType

string

param NodeType

A valid node type that you want to scale this cluster up or down to.

type EngineVersion

string

param EngineVersion

The upgraded version of the engine to be run on the nodes. You can upgrade to a newer engine version, but you cannot downgrade to an earlier engine version. If you want to use an earlier engine version, you must delete the existing cluster and create it anew with the earlier engine version.

  • ReplicaCount (integer) --

    The number of replicas to scale up or down to
