------------------------------------
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}
