| # PIP-122: Change loadBalancer default loadSheddingStrategy to ThresholdShedder |
| |
| The ThresholdShedder load balance policy since Pulsar 2.6.0 by https://github.com/apache/pulsar/pull/6772. It can resolve many load balance issues of `OverloadShedder` and works well in many Pulsar production clusters. |
| |
| In Pulsar 2.6.0, 2.7.0, 2.8.0 and 2.9.0, Pulsar's default load balance policy is `OverloadShedder`. |
| |
| I think it's a good time for 2.10 to change default load balance policy to `ThresholdShedder`, it will make throughput more balance between brokers. |
| |
| ### Proposed Changes |
| In 2.10 release,for `broker.conf`, change `loadBalancerLoadSheddingStrategy` from `org.apache.pulsar.broker.loadbalance.impl.OverloadShedder` to `org.apache.pulsar.broker.loadbalance.impl.ThresholdShedder` |
