public virtual Task<Control> CreateControl(CreateControlRequest request, ServerCallContext context)
Creates a Control.
By default 1000 controls are allowed for a data store.
A request can be submitted to adjust this limit.
If the [Control][google.cloud.discoveryengine.v1beta.Control] to create
already exists, an ALREADY_EXISTS error is returned.
public virtual Task<Control> UpdateControl(UpdateControlRequest request, ServerCallContext context)
Updates a Control.
[Control][google.cloud.discoveryengine.v1beta.Control] action type cannot
be changed. If the [Control][google.cloud.discoveryengine.v1beta.Control]
to update does not exist, a NOT_FOUND error is returned.
