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.
