filedb 0.2.3

Why?

Because our enterprise database is file based, but our cloud based database isn’t.

…no really why?

Files are simpler and don’t break. The database operations we need to perform aren’t complicated and don’t require high performance. By using files there isn’t a database that can fail. There’s the added benefit that if customers want to use different types of databases for distributed systems, we can plug into any of them using a filedb (we just have to make something that dumps out JSON .

Quickstart

$ mongod

$ mongo
> use test
> db.people.insert({"username": "greg"})
> db.people.insert({"username": "phil"})
> db.people.insert({"username": "bob"})
> db.people.insert({"username": "samantha"})

$ pip install filedb

$ filedb /tmp/tutorial/mnt/ mongodb://localhost:27017/test people

$ cat /tmp/tutorial/mnt/db
[{ "_id": "52f104a7a0fb769e0cd0d1d4", "username": "greg" }
