Mongo: avoid duplicate files in gridfs

There is a way to avoid duplicate files in mongo gridfs? Or I have to do that via application code (I am using pymongo)

The MD5 sum is already part of Mongo's gridfs meta-data, so you could simply set a unique index on that column and the server will refuse to store the file. No need to compare on the client side.

You could use md5 hash and compare new hash with exists before saving file.
