andrasbeni opened a new pull request, #16901:
URL: https://github.com/apache/pulsar/pull/16901
Fixes #15254
### Motivation
The number of topics in a namespace is limited by ZooKeeper when it is used
as the local store. This is because listing topics requires all topic names to
fit in ZK's buffer. By introducing an intermediate layer between the namespace
node and topics, a namespace can have more topics.
### Modifications
- Add new namespace policy `number_of_buckets` defaulting to 1 (i.e. no
buckets)
- Calculate topics' persistence name based on the number of buckets in the
namespace
