   > So IMHO the right direction would be either trying our best to unload 
inactive state ASAP, or considering the replication as the further improvement. 
Not somewhere in between. Even the latter wouldn't be an improvement if we 
could enforce Spark to respect the active executor of the state.
   
   Regarding "the replication", I read through the previous comments. I'm not 
pretty sure if I understand your point correctly. Is it any different than 
reusing the stores of previous batch? Because seems to me, you are against to 
have previous stores kept in TTL and reuse them, or I misread your comments? 
But the replication sounds similar to me. Can you elaborate it?
