Data Layers

The persistence of information object for long term operations is based on the implementation of a set of contracts of the management domain of the service.

Since the native support of multi-tenancy of the information, a model is in place to create tenant-specific contexts, provided throug a 'store provider' pattern.

Storage Contracts

The main contracts used to implement this persistence are the following:

Interface	Description
IWebhookSubscriptionStore	Implements the functions to manage the storage of IWebhookSubscription information
IWebhookSubscriptionStoreProvider	Provides the means to instantiate a tenant-specific context owning the webhook subscriptions
IWebhookDeliveryResultStore	Implements the functions to manage the storage of webhook delivery results
IWebhookDeliveryResultStoreProvider	Creates tenant-specific scopes for the storage of the webhook delivery results

Subscription Resolution

Although the resolution of the webhook subscriptions is not directly related to the storage of the information, the framework provides a contract to implement the resolution of the subscriptions based on the storage.

In fact, the IWebhookSubscriptionResolver interface is used by the framework to resolve the subscriptions to a specific event, and in the default implementation, it uses the IWebhookSubscriptionStore to retrieve the information.

Delivery Logging

Some advanced scenarios of usage may require to log the delivery results of the webhook notifications, to provide a way to track the delivery status of the notifications.

Even if the logging mechanism doesn't require a specific database (it might be logging on CSV files, JSON, etc.), the framework provides the contract IWebhookDeliveryResultStore to implement the storage of the delivery results.

Storage Implementations

The Deveel Webhooks framework provides the following implementations of the storage:

Implementation	Description	Subscription Store	Delivery Logging	Multi-Tenant
MongoDB Storage	Implements the storage of the webhook subscriptions and delivery results using MongoDB	✅	✅	✅
Entity Framework	An implementation that stores subcriptions and delivery results using the Entity Framework	✅	✅	❌

Refere to the specific documentation of each implementation for more details.
