    Description

      ListAllChildren and IterateChildren functions of metakv are for one time querying the key, they not suppose to be used if you want to watch for the updates

      Please use: RunObserveChildren
      Please use it just once for your most common prefix (/eventing) since each call of this method occupies one socket.

      Beauty we see in metakv.log:
