API methods such as SearchService.Search, ProductService.GetProduct, 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 to `projects/*/locations/*/catalogs/*/branches/default_branch` is equivalent to setting 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 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}.

API methods such as SearchService.Search, ProductService.GetProduct, 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 to `projects/*/locations/*/catalogs/*/branches/default_branch` is equivalent to setting 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 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](https://cloud.google.com/contact) to contact cloud sales if you are interested in using Retail Search. 321 322Args: 323 catalog: string, Full resource name of the catalog, such as `projects/*/locations/global/catalogs/default_catalog`. (required) 324 body: object, The request body. 325 The object takes the form of: 326 327{ # Request message to set a specified branch as new default_branch. 328 "branchId": "A String", # The final component of the resource name of a branch. This field must be one of "0", "1" or "2". Otherwise, an INVALID_ARGUMENT error is returned. 329 "note": "A String", # Some note on this request, this can be retrieved by CatalogService.GetDefaultBranch before next valid default branch set occurs. This field must be a UTF-8 encoded string with a length limit of 1,000 characters. Otherwise, an INVALID_ARGUMENT error is returned. 330} 331 332 x__xgafv: string, V1 error format. 333 Allowed values 334 1 - v1 error format 335 2 - v2 error format 336 337Returns: 338 An object of the form: 339 340 { # A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance: service Foo { rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty); } The JSON representation for `Empty` is empty JSON object `{}`. 341}</pre> 342</div> 343 344</body></html>
