class MemoryDB.Client

A low-level client representing Amazon MemoryDB

MemoryDB for Redis is a fully managed, Redis-compatible, in-memory database that delivers ultra-fast performance and Multi-AZ durability for modern applications built using microservices architectures. MemoryDB stores the entire database in-memory, enabling low latency and high throughput data access. It is compatible with Redis, a popular open source data store, enabling you to leverage Redis’ flexible and friendly data structures, APIs, and commands.

import boto3

client = boto3.client('memorydb')

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.

Returns
True if the operation can be paginated, False otherwise.
close()

Closes underlying endpoint connections.

copy_snapshot(**kwargs)

Makes a copy of an existing snapshot.

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. MemoryDB does not permit overwriting a snapshot, therefore this name must be unique within its context - MemoryDB 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 MemoryDB has the needed permissions to this S3 bucket. For more information, see Step 2: Grant MemoryDB Access to Your Amazon S3 Bucket .
  • KmsKeyId (string) -- The ID of the KMS key used to encrypt the target snapshot.
  • Tags (list) --

    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.

      • Value (string) --

        The tag's value. May be null.

create_subnet_group(**kwargs)

Creates a subnet group. A subnet group is a collection of subnets (typically private) that you can designate for your clusters running in an Amazon Virtual Private Cloud (VPC) environment. When you create a cluster in an Amazon VPC, you must specify a subnet group. MemoryDB uses that subnet group to choose a subnet and IP addresses within that subnet to associate with your nodes. For more information, see Subnets and subnet groups .

tag_resource(**kwargs)

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 MemoryDB resources. When you add or remove tags on clusters, those actions will be replicated to all nodes in the cluster. For more information, see Resource-level permissions .

For example, you can use cost-allocation tags to your MemoryDB 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 Using Cost Allocation Tags .
