if my node is getting frequent write requests and I want to restore the snapshots. how will it be possible? while going through the course i found 2 ways of restoring :
1. to delete the current data files and copy snapshots and incrementals to data directories. but will this not lead to inconsistent and missing data as we remove the existing data files, plus there are many write req coming on the node then what would happen?
does restore needs any downtime or it would work on already running node.
2. second way is through sstableloader
Question 2 : what if after taking snapshot or while restoring data on that node . the schema is altered / changed ? we might need to drop the older schema present and create new one ?
