As we were planning to move our terabytes of files into MongoDB GridFS, it occured to us that there is no readily available way to efficiently serve these files over the web, without resorting to using an ASP.NET GridFS IHttpHandler we implemented for local debugging some time ago.

After much hassle while developing GridFS handler for G-WAN (it is certainly fast, but keeps crashing even on Ubuntu 10.04.4 LTS, both x86 and x64 versions, even when I removed all non-boilerplate code from the module itself), performance measuring https://github.com/mdirolf/nginx-gridfs (until there is an asynchronous MongoDB driver, any GridFS module for NGINX is doomed), I decided to write an Apache 2.x (actually tested on 2.4) module to serve files from GridFS.

I decided to release it as open source here: https://bitbucket.org/onyxmaster/mod_gridfs/. It runs faster than the NGINX one, even with multiple workers, so we're going to use it as a backend (with NGINX as a caching frontend of course).

Configuration example:
GridFSConnection rsTest/db1,db2
GridFSDatabase my_database

  1. Hello.
    I'm trying to set up GridFS serving via Apache using your module, but I got stuck at using id field (which is ObjectId by default) as filename field.

    There's an attribute "GridFSFilenameField" described in your readme, but it doesn't work with "_id" field, most likely because it is not a string.

    Is there any other way to use ObjectIds as a filename?

    Thank you in advance.
