             Summary: Avoid per-host hinted-handoff throttle being rounded to 0 in large cluster
                 Key: CASSANDRA-15859
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15859
             Project: Cassandra
          Issue Type: Bug
          Components: Consistency/Hints
            Reporter: ZhaoYang


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}
