@ -11,11 +11,11 @@ The underlying distributed consensus protocol relies on two separate time parame
The first parameter is called the *Heartbeat Interval*.
This is the frequency with which the leader will notify followers that it is still the leader.
etcd batches commands together for higher throughput so this heartbeat interval is also a delay for how long it takes for commands to be committed.
By default, etcd uses a `50ms` heartbeat interval.
By default, etcd uses a `100ms` heartbeat interval.
The second parameter is the *Election Timeout*.
This timeout is how long a follower node will go without hearing a heartbeat before attempting to become leader itself.
By default, etcd uses a `200ms` election timeout.
By default, etcd uses a `1000ms` election timeout.
Adjusting these values is a trade off.
Lowering the heartbeat interval will cause individual commands to be committed faster but it will lower the overall throughput of etcd.
