Elixir client for TigerBeetle.

Check out the documentation on HexDocs. It also includes a walkthrough that can be executed on LiveBook.

The package can be installed by adding tigerbeetlex to your list of dependencies in mix.exs:

def deps do
  [
    {:tigerbeetlex, "~> 0.16.51"}
  ]
end

TigerBeetle requires the client to have the same or lower version than the server.

TigerBeetlex uses the same version number as the underlying Zig TigerBeetle client to simplify selecting the right version. This also implies that we need to wait for a new TigerBeetle release to cut a new release, but this shouldn't be a problem since TigerBeetle has a fixed weekly release schedule.

If/when TigerBeetle switches to a slower release cadence, we might evaluate using different version numbers.

Clone the repo and fetch dependencies:

$ git clone https://github.com/rbino/tigerbeetlex.git
$ cd tigerbeetlex
$ mix deps.get

In a new terminal session, download TigerBeetle using the right command for your OS:

# Linux
curl -Lo tigerbeetle.zip https://linux.tigerbeetle.com && unzip tigerbeetle.zip
# macOS
curl -Lo tigerbeetle.zip https://mac.tigerbeetle.com && unzip tigerbeetle.zip
# Windows
powershell -command "curl.exe -Lo tigerbeetle.zip https://windows.tigerbeetle.com; Expand-Archive tigerbeetle.zip"

Then create the data file and start your development cluster

./tigerbeetle format --cluster=0 --replica=0 --replica-count=1 --development 0_0.tigerbeetle
./tigerbeetle start --addresses=3000 --development 0_0.tigerbeetle

See the TigerBeetle documentation for more info.

Finally, in the first terminal, ensure the tests pass:

$ mix test
