thetumbled opened a new pull request, #22889: URL: https://github.com/apache/pulsar/pull/22889
### Motivation Initially, we introduce `loadBalancerCPUResourceWeight`, `loadBalancerBandwidthInResourceWeight`, `loadBalancerBandwidthOutResourceWeight`, `loadBalancerMemoryResourceWeight`, `loadBalancerDirectMemoryResourceWeight` in `ThresholdShedder` to control the resource weight for different resources when calculating the load of the broker. Then we let it work for `LeastResourceUsageWithWeight` for better bundle placement policy. But https://github.com/apache/pulsar/pull/19559 and https://github.com/apache/pulsar/pull/21168 have point out that the actual load of the broker is not related to the memory usage and direct memory usage, thus we have changed the default value of `loadBalancerMemoryResourceWeight`, `loadBalancerDirectMemoryResourceWeight` to 0.0. There are still some places where memory usage and direct memory usage are used to calculate the load of the broker, such as `OverloadShedder`, `LeastLongTermMessageRate`, `ModularLoadManagerImpl`. We should let the resource weight work for these places so that we can set the resource weight to 0.0 to avoid the impact of memory usage and direct memory usage on the load of the broker. ### Modifications - Let resource weight work for `OverloadShedder`, `LeastLongTermMessageRate`, `ModularLoadManagerImpl`. ### Verifying this change - [ ] Make sure that the change passes the CI checks. *(Please pick either of the following options)* This change is a trivial rework / code cleanup without any test coverage. ### Does this pull request potentially affect one of the following parts: <!-- DO NOT REMOVE THIS SECTION.
