Setting throughput limit on strimzi

[sudheesh-87]

As per the documentation, strimzi supports default kafka aswell as strimzi plugin now to configure quota at broker level , Am I right in understanding that,
strimzi - > Supports setting overall throughput limit for the brokers and it ensures dynamic distribution of the available quota among users, however there is no option to set the upper limit per user
kafka -> Supports setting throughput limit per user on the broker and there is no upper limit that can be set per broker using this plugin

Also only one of the plugins can be enabled at broker side at the same time, and the user level quota that we set using KafkaUser custom resource only works when the quota plugin enabled at broker side is kafka , it does not work with strimzi plugin .

So in this case,

1. kafka plugin or user quota is useful to prevent one rogue kafka user overwhelming the broker and causing denial of service , but doesn't provide protection against running many such rogue kafka users at the same time and loading the broker, since there is no broker level upper limit setting here .
2. strimzi plugins can help in protecting the broker against one or more rogue kafka user since there is an upper limit setting for the brokers supported, however since dynamic distribution of quota exists , one rogue kafka user can consume all the quota and deny service to other users since there is no user level upper limit .

How to prevent both of the above scenario with available options? if not available now , is there any plan for adding user level upper limit as well with strimzi plugin in the future ?

I do not think there is any plan to enhance the Strimzi plugin anytime soon. But if you would be interested in it, proposals (as it should probably start with a proposal how it would be implemented) and PRs are always welcome.
