> Currently, Pulsar exposes the message written count metrics though the
> Prometheus endpoint, and the metrics maintain in the broker, no been
> persistent. So if the topic ownership changes or restart broker, this will
> lead to reset the message written count of the topic to 0. This will confused
> users and not able to get the correct message written count metrics.

> a broker level entry metadata which can support message index for a topic(or
> message offset of a topic), this will provide the ability to calculate the
> precise message written count for a topic. So we can leverage PIP-70 to
> improve the message written count metrics for the topic
