What Do I Need To Know?

|---|---|
| Instance | A running Clortho cluster |
| Database | An organizational unit for buckets |
| Bucket | An organizational unit for keys |
| Key | A mnemonic for referencing a value |
How Do I Do It?
Set up your config file (YAML).
storage_directory: /path/to/whatever
rest_port: some_port_number
Run it.
nohup clortho -c /path/to/config
Queries
As could probably be guessed from the REST port set in the config, Clortho provides a RESTish HTTP (well, sorta) interface.
The URI scheme is http://server:port/DATABASE/BUCKET/KEY
To set a key, PUT it. To set the key "123" in the "randomnumbers" bucket in the "stuff" database from the Clortho instance running on localhost port 9001, you'll do something like the following:
curl -X PUT http://localhost:9001/stuff/randomnumbers/123 \
-H "Content-type: text/plain" \
--data "This is some random stuff right here."
To get a key, GET it. If you want the value for key "123" in the "randomnumbers" bucket in the "stuff" database from the Clortho instance running on localhost port 9001, you'll do something like this:
curl -H "Accept: text/plain" http://localhost:9001/stuff/randomnumbers/123
How Does It Work?
Right now? Barely. Hell, I haven't even written much beyond basic database and bucket handling.
It uses leveldb for actual storage. It's pretty nifty.
It's written in Ruby for now. I hope to port it to a proper compiled language at some point, preferably something a little more traditional than Erlang. Because I don't know Erlang, like, at all.
