Properties

ClientId

public string ClientId { get; set; }

Output only. The identifier of the client that originally requested this Trial. Each client is identified by a unique client_id. When a client asks for a suggestion, Vizier will assign it a Trial. The client should evaluate the Trial, complete it, and report back to Vizier. If suggestion is asked again by same client_id before the Trial is completed, the same Trial will be returned. Multiple clients with different client_ids can ask for suggestions simultaneously, each of them will get their own Trial.
