Hi dev, I realized that `removeMostServicingBrokersForNamespace` func in the broker selection logic can cause infinite unloading.
Suppose an overloaded broker unloaded a bundle and only has the minimum number of bundles(in that namespace) among brokers. In that case, the selection logic (`removeMostServicingBrokersForNamespace`) will filter out other brokers and always reassign the bundle to the previous broker. This will cause infinite unloading(like a boomerang). To mitigate this issue, we need to cherry-pick this PR to disable this logic by the config. https://github.com/apache/pulsar/pull/16059 And we probably want to disable this `removeMostServicingBrokersForNamespace` logic by default.
