Hi, I'm starting the vote for PIP-323, since it has been reviewed by several people and all comments have been resolved.
Reminder: PIP-323 is introduced to fill the gap of backlog quota telemetry. It allows the user to know when a time-based backlog quota is about to exceed, and how many times it exceeded. It also adds backlog quota check duration metric allowing the user to configure the interval for that check based on data. Once this is implemented, the user can finally create an alert to know when a certain topic is about to exceed its defined backlog quota limit, alert on it, and use topic stats Admin API to grab the subscription name causing it.
