This Recommendations AI documentation references the Recommendations console. We recommend switching to the Retail console and using the Retail documentation, which documents Recommendations AI, the Retail console, and Retail Search.

If you are using the v1beta version of Recommendations AI, migrate to the Retail API version.

Method: projects.locations.catalogs.setDefaultBranch

Set a specified branch id as default branch. 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}.

note

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.

force

boolean
