<p>To support resiliency and high availability, NATS provides built-in mechanisms to automatically prune the registered listener interest graph that is used to keep track of subscribers, including slow consumers and lazy listeners. NATS automatically handles a slow consumer. If a client is not processing messages quick enough, the NATS server cuts it off. To support scaling, NATS provides for auto-pruning of client connections. If a subscriber does not respond to ping requests from the server within the <a href="../nats-protocol/nats-protocol.md#PINGPONG">ping-pong interval</a>, the client is cut off (disconnected). The client will need to have reconnect logic to reconnect with the server.</p>

<p>In core NATS, consumers that cannot keep up are handled differently from many other messaging systems: NATS favors the approach of protecting the system as a whole over accommodating a particular consumer to ensure message delivery.</p>
