Getting started

EventStore is available in Hex and can be installed as follows:

Add eventstore to your list of dependencies in mix.exs:
```
  def deps do
    [{:eventstore, "~> 0.12"}]
  end
```

Add an eventstore config entry containing the PostgreSQL database connection details to each environment’s mix config file (e.g. config/dev.exs):

  config :eventstore, EventStore.Storage,
    serializer: EventStore.TermSerializer,
    username: "postgres",
    password: "postgres",
    database: "eventstore_dev",
    hostname: "localhost",
    pool_size: 10,
    pool_overflow: 5

The database connection pool configuration options are:

:pool_size - The number of connections (default: 10).
:pool_overflow - The maximum number of overflow connections to start if all connections are checked out (default: 0).

Create the EventStore database and tables using the mix task:
```
  $ mix event_store.create
```
