Thank you Erick, > it is going to be single-threaded by default so it will take a while to get through all the sstables on dense nodes Is there any downside if the upgradesstables take longer (example 1-2 days), other than I/O?
Also when is the upgradesstable get triggered? after every node is upgraded or it will kick in only when all the nodes in the cluster upgraded to 4.0.x?
