> URL: https://issues.apache.org/jira/browse/CASSANDRA-15859
> Project: Cassandra
> Issue Type: Bug

> Reporter: ZhaoYang

> Labels: low-hanging-fruit
> Fix For: 3.0.x, 3.11.x, 4.0-rc
>
>
> When "hinted_handoff_throttle_in_kb" is sufficiently small or num of nodes in
> the cluster is sufficiently large, the per-host throttle will be rounded to
> 0, aka. unthrottled.
>
> {code:java|title=HintsDispatchExecutor.java}
> int throttleInKB = DatabaseDescriptor.getHintedHandoffThrottleInKB() /
> nodesCount;
> this.rateLimiter = RateLimiter.create(throttleInKB == 0 ? Double.MAX_VALUE :
> throttleInKB * 1024);
> {code}
