public class KeepAliveRequest
extends AbstractRaftRequest

Session keep alive request.

Keep alive requests are sent by clients to servers to maintain a session registered via a OpenSessionRequest. Once a session has been registered, clients are responsible for sending keep alive requests to the cluster at a rate less than the provided OpenSessionResponse.timeout(). Keep alive requests also server to acknowledge the receipt of responses and events by the client. The commandSequenceNumbers() number indicates the highest command sequence number for which the client has received a response, and the eventIndexes() numbers indicate the highest index for which the client has received an event in proper sequence.
