Modified consistent hashing: Multiple copies of same shard


What if we slightly changed the ring so that instead of one copy per shard, now we have multiple copies of the same shard spread over the ring.

I didn’t understand this part. Aren’t the shard we have placed in the ring same? don’t they contain same data in all over the shards?
Or we just increase their numbers in the ring who is suggested in modified consistent hashing?

PS: I got it. Just appearing the same key(shard) in multiple possible so that chances of getting hit to that increases, this is that means.
