Tell me when will data be on more than one shard?


MongoDB sharding is range based. So all the objects in a collection get put into a chunk. Only when there is more than 1 chunk is there an option for multiple shards to get data. Right now, the default chunk size is 64mb, so you need at least 64mb for a migration to occur.
