SymmetricDS Heartbeat Delay Time
<p>I'm using bi-directional push mode with <code>sync_on_incoming_batch=1</code>.</p>

<p>Let say corp send heartbeat to <code>store-001</code>. Soon, <code>store-001</code> send heartbeat to <code>corp</code>. But the <code>node_id</code> in <code>sym_outgoing_batch</code> is <code>-1</code>.</p>

<p>Question:</p>

<ol>
<li>How long heartbeat delay time (until it send heartbeat again)?</li>
<li>I read if <code>sync_on_incoming_batch=1</code> and after <code>corp</code> sent to <code>store-001</code>, the <code>store-001</code> doesn't send it back to <code>corp</code>. Is <code>node_id=-1</code> on <code>sym_outgoing_batch</code> the sign of it?</li>
<li>If number 2 is yes, how long the expiry time occurs?</li>
</ol>
