------------------------------------
Summary: Need a way to update quota for TokenBucket registered
with Sensor
Key: KAFKA-10458
URL: https://issues.apache.org/jira/browse/KAFKA-10458
Project: Kafka
Issue Type: Improvement
Components: clients
Reporter: Anna Povzner
Assignee: Anna Povzner
Fix For: 2.7.0
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.
