## [Unreleased]

## [0.2.0] - 2022-12-05

### Features

#### Ordered event processing

When the outbox table contains a `:group_id` table (and the producer fills up events with it), then a group of events with the same `:group_id` will be processed one by one, by order of insertion.

```ruby
# migration
create_table(:outbox) do
  column :message_group_id, :integer

# tobox.rb
message_group_column :group_id

# event production
DB[:outbox].insert(event_type: "order_created", message_group_id: order.id, ....
DB[:outbox].insert(event_type: "billing_event_started", message_group_id: order.id, ....

# order_created handled first, billing_event_started only after
```

#### on_error_worker callback

The config option `on_error_worker { |error| }` gets called when an error happens in a worker **before** events are processed (p.ex. when the database connection becomes unhealthy). You can use it to report such errors to an error reporting system (the `sentry` plugin relies on it).

```ruby
# tobox.rb
on_error_worker { |error| Sentry.capture_exception(error, hint: { background: false }) }
```

### Bugfixes

Thread workers: when errors happen which bring down the workers (such as database becoming unresponsive), workers will be restarted.
