 The [optimistic transaction](/optimistic-transaction.md) model commits the transaction directly, and rolls back when there is a conflict. By contrast, the [pessimistic transaction](/pessimistic-transaction.md) model tries to lock the resources that need to be modified before actually committing the transaction, and only starts committing after ensuring that the transaction can be successfully executed.
