   ah, wasn't realized this! thanks for the reference! I'll give a through read 
over the weekend. Our use case is to calculate the max slots required, so the 
cluster has enough resources before deploying. IIUC, different slot sharing 
group can't schedule on the same slot, so adding slot sharing group has the 
implication on increasing parallelism/slots required, so we don't concern about 
if operators in the same sharing group are deployed together or not. i.e. `max 
slots required = sum(max parallelism of each slot sharing group)`
   
   Is my understanding correct?
