   @slfan1989 Hi, I found that newly submitted apps may be mistakenly deleted 
in Delete triggered condition 1:
   If an app was submitted to Router, the Router stores this app in state 
store, but it hasn't been submitted to SubCluster. At this time, the CleanUp 
thread compares the lists queried in the state store and the SubCluster. This 
app exists in the state store but not in the SubCluster, so it will be 
mistakenly deleted.
