Sorry for the typo. I rewrite my question again: I just created a 90gb index collection with 1 shard and 2 replicas on 2 nodes. I am to migrate from 2 nodes to 4 nodes. I am wondering what's the best strategy to split this single shard? Furthermore, if I am ok to reindex, what's the best adequate experienced values of numShards and replicationFactor? Lastly, If I add new shard(s), I think there's no other way but reindex if I want my data to be evenly distributed into every shard, right?
