Review comment:
       I don't think we have finalized the streaming writing semantic yet. Ideally, it should be similar to batch (upsert semantic), but we are not at that point yet.
   
   I think we should standardize the streaming writing query plan later. For now, let's just use one query plan with `OutputMode` as the parameter.
