> The follower/observer enable read only. When the node returns to normal from
> the partitioned, the ephemerals nodes will be inconsistent with the leader
> node. The reason is that the request to close the timeout sessions is
> processed by the ReadOnly follower or observer when they are partitioned and
> the ephemerals nodes created by these sessions also are delete. When the
> leader node uses diff to synchronize data with the follower/observer node,
> the transaction that needs to be synchronized does not include the creation
> of temporary nodes which created by sessions closed by followers.So the
> follower/observer ephemerals nodes is inconsistent with leader.
