org.apache.kafka.common.errors.DisconnectException

The `org.apache.kafka.common.errors.DisconnectException` is an exception in Apache Kafka that indicates a disconnection between a client and a broker. This exception can occur when the client or broker closes the connection unexpectedly, which can happen due to a variety of reasons such as network issues, system failures, or misconfigured settings.

When this exception occurs, the client can attempt to reconnect to the broker to resume communication. However, it's important to investigate the root cause of the disconnection to prevent it from happening again in the future. The `DisconnectException` can also lead to data loss or message duplication, so it's critical to handle this exception properly in your Kafka application.
