GenServer that periodically cleans up expired and consumed BankID orders.

This process prevents the indefinite accumulation of orders in the database by deleting:

• Orders that have exceeded their TTL (expired)
• Consumed orders that are older than the retention period

Configuration

The Expunger is configured through the BankID strategy DSL:

bank_id do
  order_resource MyApp.Accounts.BankIDOrder
  cleanup_interval 300_000  # 5 minutes in milliseconds
  consumed_order_ttl 86_400  # 24 hours in seconds
end

Configuration options:

• cleanup_interval: How often to run cleanup (default: 5 minutes)
• order_ttl: How long orders are valid (inherited from strategy)
• consumed_order_ttl: How long to retain consumed orders (default: 24 hours)

Usage

The Expunger should be added to your application's supervision tree:

children = [
  # ... other children
  {AshAuthentication.BankID.Expunger,
   order_resource: MyApp.Accounts.BankIDOrder,
   order_ttl: 300,
   cleanup_interval: 300_000,
   consumed_order_ttl: 86_400}
]

Manual Cleanup

You can trigger a manual cleanup (useful for testing):

AshAuthentication.BankID.Expunger.trigger_cleanup()
