<div dir="ltr">We will have approximately 300 open active connections due to the shovel configurations setup. These are the IN/OUT queues setup. I have a consumer service on the client side that'll open the conn/channel, get messages from the queue, ack it, and then close the connection. If the client fail to issue the close connection service, RabbitMQ should close that specific channel/connection if I set the "setRequestedHeartBeat" in the open connection service, right?</div>

</div>Hearbeats allow RabbitMQ and compliant clients detect peer disappearance quicker<br>
(than via TCP connection closure). It only affects connections.<br>
<br>
There is no harm in using heartbeats, just make sure that the value is not too high<br>
or two low. Lower values means quicker connection loss detection but increase network traffic<br>
and slightly increase server load per connection.<br>
Heartbeat frames will be sent at roughly half the interval (so, if the timeout is set to<br>
100 seconds, a little bit of data will be sent every ~50 seconds from both ends). After<br>
two missed heartbeats (full interval duration), RabbitMQ will consider the connection closed.<br>
<br>
Unless you have hundreds of connections, any value between 60 and 180 should be fine.<br>
