2. Ensure tarantool is started before your application:

   def application do [applications: [:tarantool]] end

Usage Examples

iex(1)> : {:ok, t} = Tarantool.start_link
{:ok, #PID<0.129.0>}

iex(2)>  Tarantool.Api.auth(t, %{password: "111222", username: "amalaev"})
{:ok, %{}}

iex(3)>  Tarantool.Api.select(t, %{space_id: 280, limit: 100, key: [], index_id: nil, iterator: nil, offset: 100})
{:ok, []}

iex(4)> Tarantool.Api.select(t, %{space_id: 280, limit: 100, key: [], index_id: nil, iterator: nil, offset: 0})
