URL: https://github.com/apache/kafka/pull/21160
This PR implements KAFKA-18615 by adding a windowSum aggregation that
computes the sum of values over a time window, so that `commit-ratio`,
`poll-ratio`, `process-ratio`, and `punctuate-ratio` represent the ratio of the
`{action}` over a window duration rather than a single iteration.
The effective window duration is whatever you configure for metrics:
- `metrics.sample.window.ms` (per-sample window length)
- `times metrics.num.samples` (number of rolling windows)
With the default Kafka metrics config, that is typically:
`metrics.sample.window.ms = 30000 ms`
`metrics.num.samples = 2`
→ ~60 seconds total rolling window.
