# Ram
**Ram** is an in-memory distributed KV store for Erlang and Elixir, able to automatically manage dynamic clusters
(addition / removal of nodes) and to recover from net splits.
Ram operations are **A**tomic (take effect on all nodes involved, or on none of the nodes),
**C**onsistent (the data is the same across all nodes)
and **I**solated (operations on different nodes in a network do not interfere with each other).
They are not **D**urable since Ram is an in-memory only database.
Ram is an experiment and at an early development stage.
## Installation
### For Elixir
Add it to your deps:
```elixir
defp deps do
[{:ram, "~> 0.0.1"}]
end
```
### For Erlang
If you're using [rebar3](https://github.com/erlang/rebar3), add `ram` as a dependency in your project's `rebar.config` file:
```erlang
{deps, [
{ram, {git, "git://github.com/ostinelli/ram.git", {tag, "0.0.1"}}}
]}.
```
Or, if you're using [Hex.pm](https://hex.pm/) as package manager (with the [rebar3_hex](https://github.com/hexpm/rebar3_hex) plugin):
```erlang
{deps, [
{ram, "0.0.1"}
]}.
```
Ensure that `ram` is started with your application, for example by adding it in your `.app` file to the list of `applications`:
```erlang
{application, my_app, [
%% ...
{applications, [
kernel,
stdlib,
sasl,
ram,
%% ...
]},
%% ...
]}.
```
## Contributing
So you want to contribute? That's great! Please follow the guidelines below. It will make it easier to get merged in.
Before implementing a new feature, please submit a ticket to discuss what you intend to do. Your feature might already be in the works, or an alternative implementation might have already been discussed.
Do not commit to master in your fork. Provide a clean branch without merge commits. Every pull request should have its own topic branch. In this way, every additional adjustments to the original pull request might be done easily, and squashed with `git rebase -i`. The updated branch will be visible in the same pull request, so there will be no need to open new pull requests when there are changes to be applied.
Ensure that proper testing is included. To run Syn tests you simply have to be in the project's root directory and run:
```bash
$ make test
```
