MasDB

MasDB is a distributed database.

Build

You need to have elixir and erlang installed on your system. Run mix deps.get to get all dependencies.

Run

Before being able to run a node, you need to have epmd running. You can start it as a daemon with epmd -daemon.

There's some environment variables that can be changed to setup a MasDB node.

  SAVE_FILE    Set the save path. Default to `./data.db`.
  NODE_NAME    Set this erlang's node's fully qualified name. In release, if this is not set, the node won't start.
                eg. `foo@127.0.0.1`
  NODE_TO_JOIN Set the node that this node need to contact to join a cluster. eg. `name@hostname`

A simple way to configure a node is to create a .env file and run source .env before launching the code.

.env1

export SAVE_FILE=./data/foo.db
export NODE_NAME=foo@127.0.0.1
export REPLACE_OS_VARS=true

.env2

export SAVE_FILE=./data/bar.db
export NODE_NAME=bar@127.0.0.1
export NODE_TO_JOIN=foo@127.0.0.1
export REPLACE_OS_VARS=true

It's also possible to modify environment variables while launching the node.

$ NODE_NAME=bar iex -S mix

Release

Running mix release should produce a release using distillery.
