Tsz-wo Sze commented on RATIS-1622:
-----------------------------------
bq. ... if the follower is down, then it will keep looping, right? ...
Right, shouldSendAppendEntries() will keep returning true. How about we
enforce a min wait time as below?
{code}
static final long WAIT_TIME_MIN_MS = 10L;
private long getWaitTimeMs() {
final long lastHeartbeatElapsedMs =
getFollower().getLastHeartbeatSendTime().elapsedTimeMs();
if (lastHeartbeatElapsedMs < WAIT_TIME_MIN_MS) {
return WAIT_TIME_MIN_MS - lastHeartbeatElapsedMs;
}
return shouldSendAppendEntries()? 0L: getHeartbeatWaitTimeMs();
}
{code}
