问题:

I need to store a large number of images (from around 10,000 images per day) With an average size of around 1 to 10 MB for each image.

I can store these images in MongoDB using the GridFS Library or by just storing the Base64 conversion as a string.

My question is that, is MongoDB suitable for such a payload or is it better to use a file system?

Many Thanks,

回答1:

MongoDB GridFS has a lot of advantages over a normal file system and it is definitely able to cope with the amount of data you are describing as you can scale out with a sharded mongo cluster. I have not saved that much binary data in it on my own but I do not think there is a real difference between the binary data and text. So: yes, it is suitable for the payload.

Implementing queries and operations on the file objects being saved is easier with GridFS. In addition, GridFS caters for backup/replication/scaling. However, serving the files is faster using Filesystem + Nginx than GridFS + Nginx(look here: https://www.coffeepowered.net/2010/02/17/serving-files-out-of-gridfs/). GridFS 'slower' serving speed can however be leveraged when sharding is used
