>
> For Rate() metric with quota config, we update quota by updating config of
> KafkaMetric. However, it is not enough for TokenBucket, because it uses quota
> config on record() to properly calculate the number of tokens. Sensor passes
> config stored in the corresponding StatAndConfig, which currently never
> changes. This means that after updating quota via KafkaMetric.config, our
> current and only method, Sensor will record the value using old quota but
> then measure the value to check for quota violation using the new quota
> value.
