Avoid per-host hinted-handoff throttle being rounded to 0 in large cluster

    XMLWordPrintableJSON

Details

    Description

      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.

       

      HintsDispatchExecutor.java
      int throttleInKB = DatabaseDescriptor.getHintedHandoffThrottleInKB() / nodesCount;
this.rateLimiter = RateLimiter.create(throttleInKB == 0 ? Double.MAX_VALUE : throttleInKB * 1024);
