Is any way to restructure MongoDB?
The feature you are describing is a clustered index, which MongoDB (as at 3.2) does not support.

The most relevant feature request to upvote/watch is currently SERVER-3294.


  I am looking for something like creating chunk in NOT sharded environment.


Chunks in a MongoDB sharded cluster are metadata representing contiguous ranges of shard keys. All documents for a given chunk range will exist on the same shard, but the chunk does not currently determine the locality of data on disk.
