Hi all, I'm suggesting that we cherry-pick "PIP-442: Add memory limits for CommandGetTopicsOfNamespace and CommandWatchTopicList on Broker and Proxy" (https://github.com/apache/pulsar/blob/master/pip/pip-442.md) changes to branch-4.0. PIP-442 doesn't introduce breaking changes.
The first part of PIP-442 has been implemented by PR https://github.com/apache/pulsar/pull/24427 to cover memory limits for CommandGetTopicsOfNamespace in Broker and Proxy. PR is https://github.com/apache/pulsar/pull/24833 I'll proceed with cherry-picking PR 24833 to branch-4.0 after 24 hours unless there are objections. -Lari
