Awesome, I JUST started using ArangoDB for my latest project. So far so good, and these changes look solid. Only thing I wish they had(unless I'm missing something), is a GridFS type storage.
Interesting, not sure I want to go down that route of creating a separate Foxx service to essentially shoehorn in blobs. We'll see what happens in the future, when that becomes native. But since you guys love incorporating many types of databases into one, add ArangoFS ;)
Pure curiosity, why do you miss GridFS? I think ArangoDB it already does that, back in time there was journal size setting, I'm not sure if it still has.
I need a simple way to store a lot of photos, GridFS interface is simple, and I don't have to worry about screwing around with filesystems / folder structures. Mongo takes cares of all the sharding and what not. One man operation here!
