Undefined Kafka allows to set a default quota for all users using the Kafka Admin API:
bin/kafka-configs.sh --bootstrap-server localhost:9092 --alter --add-config 'producer_byte_rate=1024,consumer_byte_rate=2048,request_percentage=200' --entity-type users --entity-default
But it seems to conflict with the User Operator:
2023-09-08 11:56:57 ERROR AbstractCache:149 - QuotasCache failed to update java.lang.NullPointerException: null at java.util.concurrent.ConcurrentHashMap.putVal(ConcurrentHashMap.java:1011) ~[?:?] at java.util.concurrent.ConcurrentHashMap.put(ConcurrentHashMap.java:1006) ~[?:?] at io.strimzi.operator.user.operator.cache.QuotasCache.loadCache(QuotasCache.java:56) ~[io.strimzi.user-operator-0.38.0-SNAPSHOT.jar:0.38.0-SNAPSHOT] at io.strimzi.operator.user.operator.cache.AbstractCache.updateCache(AbstractCache.java:146) ~[io.strimzi.user-operator-0.38.0-SNAPSHOT.jar:0.38.0-SNAPSHOT] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:539) ~[?:?] at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:305) ~[?:?] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:305) ~[?:?] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) ~[?:?] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) ~[?:?] at java.lang.Thread.run(Thread.java:833) ~[?:?]
We should try to look if we can make it both work together - probably by ignoring the default quota in UO.
