I agree of this inconsistent scenario: ``` in-memory based validDocIds is a bit dangerous as it will not give us the consistency (e.g. fetching validDocIds bitmap while the server is restarting & updating validDocIds) ``` Also the implementation presently doesn't cover the scenario for `validDocIds` as validDocIdType in the generator task. -- This is an automated message from the Apache Git Service.
