Vladislav Pyatkov updated IGNITE-24789:
---------------------------------------
Description:
h3. Motivation
After the ticket IGNITE-24484 had been implemented, we started sending a single
heartbeat coalescence message. But we still trigger a heartbeat for each RAFT
goup:
{code}
private void startHeartbeatTimer(final long startMs) {
final long dueTime = startMs + this.options.getDynamicHeartBeatTimeoutMs();
try {
this.heartbeatTimer = this.timerManager.schedule(() ->
onTimeout(this.id), dueTime - Utils.nowMs(),
TimeUnit.MILLISECONDS);
}
catch (final Exception e) {
LOG.error("Fail to schedule heartbeat timer", e);
onTimeout(this.id);
}
}
{code}
It takes additional processing time and makes us wait for a collecting batch.
h3. Definition of done.
Replace the coalescing approach to the direct trigger heartbeat for all RAFT
groups, which would send on one message.
