@James Dennis (jtmes)
I believe your understanding on #2 is correct.
The root cause for this issue is that the aggregate's operation
sequence on DB may not exactly as same as on scheduler.
for example:
operation on DB:
1. add host
2. del host
however, on scheduler, if the operation's sequence reversed as:
1. del host
2. add host
it will case the DB/scheduler outer-sync.
