Is there any way to shard the gridFS files and chunks based on a location information ?

I want to setup a mongo configuration with sharding and replication for handling multi-sites and guaranteeing that the data produced on one site remains accessible even if the sites are isolated.

I followed the following documentation from mongo and it works just perfectly for the standard collections but not for GridFS.

https://docs.mongodb.com/v3.2/tutorial/sharding-segmenting-data-by-location/

All I found for GridFS was _id based or file_id based sharding. By now the only solution I have would be to use different GridFS prefixes which means different collections and to shard them each on a given site.

I'm using :

• mogodb 3.2
• Java driver
• Python driver

Thanks for any advice.
