CatalogService

class google.cloud.retail_v2.services.catalog_service.CatalogServiceAsyncClient(*, credentials: google.auth.credentials.Credentials = None, transport: Union[str, google.cloud.retail_v2.services.catalog_service.transports.base.CatalogServiceTransport] = 'grpc_asyncio', client_options: <module 'google.api_core.client_options' from '/workspace/.nox/docs/lib/python3.8/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>)[source]

Service for managing catalog configuration.

Instantiates the catalog service client.

Parameters
  • 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, CatalogServiceTransport]) – 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.

Raises

google.auth.exceptions.MutualTlsChannelError – If mutual TLS transport creation failed for any reason.

async set_default_branch(request: Optional[google.cloud.retail_v2.types.catalog_service.SetDefaultBranchRequest] = None, *, catalog: Optional[str] = None, retry: google.api_core.retry.Retry = <object object>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())None[source]

Set a specified branch id as default branch. API methods such as [SearchService.Search][google.cloud.retail.v2.SearchService.Search], [ProductService.GetProduct][google.cloud.retail.v2.ProductService.GetProduct], [ProductService.ListProducts][google.cloud.retail.v2.ProductService.ListProducts] will treat requests using “default_branch” to the actual branch id set as default.

For example, if projects/*/locations/*/catalogs/*/branches/1 is set as default, setting [SearchRequest.branch][google.cloud.retail.v2.SearchRequest.branch] to projects/*/locations/*/catalogs/*/branches/default_branch is equivalent to setting [SearchRequest.branch][google.cloud.retail.v2.SearchRequest.branch] to projects/*/locations/*/catalogs/*/branches/1.

Using multiple branches can be useful when developers would like to have a staging branch to test and verify for future usage. When it becomes ready, developers switch on the staging branch using this API while keeping using projects/*/locations/*/catalogs/*/branches/default_branch as [SearchRequest.branch][google.cloud.retail.v2.SearchRequest.branch] to route the traffic to this staging branch.

CAUTION: If you have live predict/search traffic, switching the default branch could potentially cause outages if the ID space of the new branch is very different from the old one.

More specifically:

  • PredictionService will only return product IDs from branch {newBranch}.

  • SearchService will only return product IDs from branch {newBranch} (if branch is not explicitly set).

  • UserEventService will only join events with products from branch {newBranch}.

This feature is only available for users who have Retail Search enabled. Please submit a form here to contact cloud sales if you are interested in using Retail Search.

Parameters
  • request (google.cloud.retail_v2.types.SetDefaultBranchRequest) – The request object. Request message to set a specified branch as new default_branch.

  • catalog (str) –

    Full resource name of the catalog, such as projects/*/locations/global/catalogs/default_catalog.

    This corresponds to the catalog field on the request instance; if request is provided, this should not be set.

  • retry (google.api_core.retry.Retry) – Designation of what errors, if any, should be retried.

  • timeout (float) – The timeout for this request.

  • metadata (Sequence[Tuple[str, str]]) – Strings which should be sent along with the request as metadata.

    If the [Catalog][google.cloud.retail.v2.Catalog] to update does not exist, a NOT_FOUND error is returned.

    This corresponds to the catalog field on the request instance; if request is provided, this should not be set.

  • update_mask (google.protobuf.field_mask_pb2.FieldMask) –

    Indicates which fields in the provided [Catalog][google.cloud.retail.v2.Catalog] to update.

Raises

google.auth.exceptions.MutualTLSChannelError – If mutual TLS transport creation failed for any reason.

Releases underlying transport’s resources.

Warning

ONLY use as a context manager if the transport is NOT shared with other clients! Exiting the with block will CLOSE the transport and may cause errors in other clients!

A pager for iterating through list_catalogs requests.

This class thinly wraps an initial google.cloud.retail_v2.types.ListCatalogsResponse object, and provides an __aiter__ method to iterate through its catalogs field.

All the usual google.cloud.retail_v2.types.ListCatalogsResponse attributes are available on the pager. If multiple requests are made, only the most recent response is retained, and thus used for attribute lookup.

Instantiates the pager.
