>          Issue Type: Improvement

> 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.
