One of my index in elasticsearch has a shard which is unassigned therefore that data is not available and my cluster status is red ,
I want to restore this index i have a snapshot of the same , so i want to restore this index from the snapshot
Now i see 2 options of doing so
delete current index and then restore from backup
close current index and restore from backup
considering my index number of shards remain the same what is the advantage of closing the index and restoring rather than deleting it and then restoring it.
