Class CloudRedisAsyncClient (2.0.0)

CloudRedisAsyncClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.redis_v1.services.cloud_redis.transports.base.CloudRedisTransport] = 'grpc_asyncio', client_options: <module 'google.api_core.client_options' from '/workspace/python-redis/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Configures and manages Cloud Memorystore for Redis instances

Google Cloud Memorystore for Redis v1

The redis.googleapis.com service implements the Google Cloud Memorystore for Redis API and defines the following resource model for managing Redis instances:

The service works with a collection of cloud projects, named: /projects/*
Each project has a collection of available locations, named: /locations/*
Each location has a collection of Redis instances, named: /instances/*
As such, Redis instances are resources of the form: /projects/{project_id}/locations/{location_id}/instances/{instance_id}

Note that location_id must be referring to a GCP region; for example:

projects/redpepper-1290/locations/us-central1/instances/my-redis

Methods

CloudRedisAsyncClient

CloudRedisAsyncClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.redis_v1.services.cloud_redis.transports.base.CloudRedisTransport] = 'grpc_asyncio', client_options: <module 'google.api_core.client_options' from '/workspace/python-redis/.nox/docfx/lib/python3.9/site-packages/google/api_core/client_options.py'> = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiate the cloud redis client.

Parameters
Name	Description
`credentials`	`Optional[google.auth.credentials.Credentials]` The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.
`transport`	`Union[str, .CloudRedisTransport]` The transport to use. If set to None, a transport is chosen automatically.
`client_options`	`ClientOptions` Custom options for the client. It won't take effect if a `transport` instance is provided. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the `api_endpoint` property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.

Exceptions
Type	Description
`google.auth.exceptions.MutualTlsChannelError`	If mutual TLS transport creation failed for any reason.

create_instance

create_instance(request: Optional[google.cloud.redis_v1.types.cloud_redis.CreateInstanceRequest] = None, *, parent: Optional[str] = None, instance_id: Optional[str] = None, instance: Optional[google.cloud.redis_v1.types.cloud_redis.Instance] = None, retry: google.api_core.retry.Retry = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())

Creates a Redis instance based on the specified tier and memory size.

By default, the instance is accessible from the project's default network <https://cloud.google.com/vpc/docs/vpc>__.

The creation is executed asynchronously and callers may check the returned operation to track its progress. Once the operation is completed the Redis instance will be fully functional. Completed longrunning.Operation will contain the new instance object in the response field.

The returned operation is automatically deleted after a few hours, so there is no need to call DeleteOperation.

`parent`	`str` Required. The resource name of the instance location using the form: `projects/{project_id}/locations/{location_id}` where `location_id` refers to a GCP region. This corresponds to the `parent` field on the `request` instance; if `request` is provided, this should not be set.
`instance_id`	`str` Required. The logical name of the Redis instance in the customer project with the following restrictions: - Must contain only lowercase letters, numbers, and hyphens. - Must start with a letter. - Must be between 1-40 characters. - Must end with a number or a letter. - Must be unique within the customer project / location This corresponds to the `instance_id` field on the `request` instance; if `request` is provided, this should not be set.
