# Persist

GenStage-based persistence layer guaranteeing at-least-once delivery of the

events.

## Installation

If [available in Hex](https://hex.pm/docs/publish), the package can be installed as:

  1. Add `persist` to your list of dependencies in `mix.exs`:

    ```elixir

    def deps do

      [{:persist, "~> 0.1.0"}]

    end

    ```

  2. Ensure `persist` is started before your application:

    ```elixir

    def application do

      [applications: [:persist]]

    end

    ```

If [published on HexDocs](https://hex.pm/docs/tasks#hex_docs), the docs can

be found at [https://hexdocs.pm/persist](https://hexdocs.pm/persist)

## Usage

```elixir

{:ok, _} = Persist.start_link(EventBus, path: "./data")

# Insert some events into the EventBus

{:ok, producer} = GenStage.from_enumerable(1..1000)

GenStage.sync_subscribe(Persist.consumer(EventBus), to: producer)

# Consume the events

GenStage.stream([Persist.producer(EventBus, :my_subscription)])

|> Enum.each(fn {ack_ref, event} ->

  Persist.ack(ack_ref)

  IO.inspect event

end)

```
