   * Thrown when the connection on which a request was executing is closed due to an unrelated event.

   * <p>For example, this can happen if the node is unresponsive and a heartbeat query failed, or if
   * the node was forced down.
   *
   * <p>The driver will retry these requests on the next node transparently, unless the request is not
   * idempotent. Therefore, this exception is usually observed as part of an {@link
