Jackie-Jiang opened a new pull request, #11393: URL: https://github.com/apache/pinot/pull/11393
Currently we use server tag to determine the worker for intermediate stage, and it has the following issues: - Maintaining the table to tag mapping in `BrokerRoutingManager` is super expensive. It reads all table configs for each instance config change (this can result in millions of read when rolling restart all servers for a large cluster) - It has a bug that only change from new enabled servers can be picked up. Changes to existing servers cannot be picked up - When instance assignment config is used, server tag is ignored, so the mapping will be wrong To address the above issues, instead of using tag to determine servers, directly picking the serving servers from the `InstanceSelector`. -- This is an automated message from the Apache Git Service.
