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, "~> 0.13"}] 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 do event_store.create, event_store.init
Initialize an existing database
You can use an existing PostgreSQL database with EventStore by running the mix
task:
$ mix event_store.init
Reset an existing database
To drop an existing EventStore database and recreate it you can run the mix
task:
$ mix event_store.reset
Warning this will delete all EventStore data.
