Review Comment:
   > And what should he do when the partition is restored
   
   After enabling dynamic partition discovery, the next fetch will occur once 
the partition is restored. If it is not enabled, data will only be written to 
partitions with an existing leader. I think this will not negatively impact the 
user.
