codelipenghui opened a new pull request #6241: Supports evenly distribute topics count when splits bundle URL: https://github.com/apache/pulsar/pull/6241 ### Motivation Currently, bundle split splits the bundle into two parts of the same size. When there are fewer topics, bundle split does not work well. The topic assigned to the broker according to the topic name hash value, hashing is not effective in a small number of topics bundle split. So, this PR introduces an option(-balance-topic-count) for bundle split. When setting it to true, the given bundle splits to 2 parts, each part has the same amount of topics. And introduce a new Load Manager implementation named `org.apache.pulsar.broker.loadbalance.impl.BalanceTopicCountModularLoadManager`. The new Load Manager implementation splits bundle with balance topics count, others are not different from ModularLoadManagerImpl. ### Verifying this change Test is coming ### Does this pull request potentially affect one of the following parts: *If `yes` was chosen, please highlight the changes* - Dependencies (does it add or upgrade a dependency): (no) - The public API: (no) - The schema: (no) - The default values of configurations: (no) - The wire protocol: (no) - The rest endpoints: (no) - The admin cli options: (no) - Anything that affects deployment: (no) ### Documentation - Does this pull request introduce a new feature?
