I'm looking at document databases for my ASP.NET MVC application, and I need something that I can embed into my application, but is also free. I have a public web site that I'm not making money off yet, but may in the future. That said, I noticed the following about these servers:
- RavenDB not free for commercial use in embedded form
- MongoDB free, but not natively embeddable. Some have gotten it to embed, but it may require AGPL licensing, which I can't do if this is true (Can mongodb be used as an embedded database?).
- db40 not free for commercial use where the source isn't generally available.
Is there any out there that are fast and free? Again, I CANNOT host it as a server, but need an embeddable database into the application.
Thanks.
