Hi, I just happen to read this part source code. TopicsPattern only works
for persistent topics, and is triggered by MetaStore notification. It seems
non-persistent topic metadata is not stored in
/managed-ledgers/tenant/namespace path, so it won't be notified.
```java
Pattern namespaceNameToTopicNamePattern(NamespaceName namespaceName) {
return Pattern.compile(
MANAGED_LEDGER_PATH + "/(" + namespaceName + ")/(" +
TopicDomain.persistent + ")/(" + "[^/]+)");
}
public void registerPersistentTopicListener(
NamespaceName namespaceName, BiConsumer<String, NotificationType>
listener) {
topicListeners.put(listener,
namespaceNameToTopicNamePattern(namespaceName));
}
```
