tjiuming opened a new pull request, #15869:
URL: https://github.com/apache/pulsar/pull/15869

   ### Motivation
   
   There was already had
   ``` java
   LoadingCache<String, TopicName> cache = CacheBuilder.newBuilder().maximumSize(100000)
               .expireAfterAccess(30, TimeUnit.MINUTES).build(new CacheLoader<String, TopicName>() {
                   @Override
                   public TopicName load(String name) throws Exception {
                       return new TopicName(name);
                   }
               });
   ```
    in `TopicName`, so that we don't need `topic -> namespace cache` in `LedgerOffloaderStatsImpl` any more.
