Configuration Management

We need a mechanism to configure the default quotas and the per-user overrides. There is general agreement that we eventually need dynamic configs per-user to fully operationalize quotas but for the purposes of this proposal, we will proceed with static configs.

Code Block
// Default bytes-out per consumer.
quota.consumer.default=2M
quota.producer.default=2M
 
// Overrides
quota.producer.override="clientA:4M;clientB:10M"
quota.consumer.override="clientC:3M;clientD:5M"

There is a separate discussion for dynamic configs per-user that isn't fully fleshed out. If it makes sense and people agree on a final design, we can model quotas using it.

 

Tooling/Monitoring Changes

Upon implementation, we will start exposing per-client byte rate metrics metrics to JMX. Since these are new metrics there are no backward compatibility issues. These metrics will be documented prior to the release.
