                supported. If not set, all supported fields (the fields
                that are neither immutable nor output only) are updated.

                If an unsupported or unknown field is provided, an
                INVALID_ARGUMENT error is returned.

                The attribute key can be updated by setting the mask

        updating fulfillment information. If the request is valid, the
        update is enqueued and processed downstream. As a consequence,
        when a response is returned, updates are not immediately
        manifested in the [Product][google.cloud.retail.v2alpha.Product]
        queried by
        [ProductService.GetProduct][google.cloud.retail.v2alpha.ProductService.GetProduct]
        or
        [ProductService.ListProducts][google.cloud.retail.v2alpha.ProductService.ListProducts].

        When inventory is updated with
        [ProductService.CreateProduct][google.cloud.retail.v2alpha.ProductService.CreateProduct]
        and
        [ProductService.UpdateProduct][google.cloud.retail.v2alpha.ProductService.UpdateProduct],
        the specified inventory field value(s) overwrite any existing
        value(s) while ignoring the last update time for this field.
        Furthermore, the last update times for the specified inventory
        fields are overwritten by the times of the
        [ProductService.CreateProduct][google.cloud.retail.v2alpha.ProductService.CreateProduct]
        or
        [ProductService.UpdateProduct][google.cloud.retail.v2alpha.ProductService.UpdateProduct]
        request.

        If no inventory fields are set in
        [CreateProductRequest.product][google.cloud.retail.v2alpha.CreateProductRequest.product],
        then any pre-existing inventory information for this product is
        used.

        If no inventory fields are set in
        [SetInventoryRequest.set_mask][google.cloud.retail.v2alpha.SetInventoryRequest.set_mask],
        then any existing inventory information is preserved.

        Pre-existing inventory information can only be updated with
        [ProductService.SetInventory][google.cloud.retail.v2alpha.ProductService.SetInventory],
        [ProductService.AddFulfillmentPlaces][google.cloud.retail.v2alpha.ProductService.AddFulfillmentPlaces],
        and
        [ProductService.RemoveFulfillmentPlaces][google.cloud.retail.v2alpha.ProductService.RemoveFulfillmentPlaces].

        The returned [Operation][google.longrunning.Operation]s is
        obsolete after one day, and the
        [GetOperation][google.longrunning.Operations.GetOperation] API
        returns ``NOT_FOUND`` afterwards.

        If conflicting updates are issued, the
        [Operation][google.longrunning.Operation]s associated with the
        stale updates are not marked as
        [done][google.longrunning.Operation.done] until they are
        obsolete.

                If the [Product][google.cloud.retail.v2alpha.Product] to

                The caller can clear all place IDs from a subset of
                fulfillment types in the following ways:

                -  Adds "fulfillment_info" in
                   [SetInventoryRequest.set_mask][google.cloud.retail.v2alpha.SetInventoryRequest.set_mask]
                -  Specifies only the desired fulfillment types to clear

                will be ignored.

                This corresponds to the ``set_mask`` 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,
