Penghui Li reopened PULSAR-9: ----------------------------- > Improve the message written count metrics for the topic > ------------------------------------------------------- > > Key: PULSAR-9 > URL: https://issues.apache.org/jira/browse/PULSAR-9 > Project: Pulsar > Issue Type: Improvement > Reporter: Penghui Li > Priority: Major > Labels: Pulsar, gsoc, gsoc2021, mentor > Original Estimate: 72h > Remaining Estimate: 72h > > 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. > PIP-70 > https://github.com/apache/pulsar/wiki/PIP-72%3A-Introduce-Pulsar-Interface-Taxonomy%3A-Audience-and-Stability-Classification > Introduced 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 -- This message was sent by Atlassian Jira (v8.3.4#803005)
