npawar opened a new pull request #3721: Add metric to capture max queries per 10s seen in the last minute URL: https://github.com/apache/incubator-pinot/pull/3721 We don't have a very good way of knowing what was the QPS for a table at a given time. Currently, whenever we receive a query, we emit a "1" in the `QUERIES` BrokerMeter. This doesn't really give us the rate of queries over a smaller chunk of time, say QPS. This can be solved in metrics viewing applications, by showing average values over a period of time. However, we will lose spikes in queries if the chunk of time is even slightly big (say 1 minute). Introducing a gauge to capture max qps in the last minute, to give us an accurate look into qps received by the broker. Starting with buckets of 10s (instead of 1s i.e. queries per 10 sec)
