Raycynix.Extensions.Messaging.Database 1.0.0

Raycynix.Extensions.Messaging.Database

Raycynix.Extensions.Messaging.Database adds persistent inbox and outbox storage for Raycynix messaging on top of Raycynix.Extensions.Database.

What it contains

• AddDatabasePersistence(...)
• persistent IIncomingMessageInboxStore
• persistent IMessageOutboxStore
• EF Core configurators registered into the shared DatabaseContext
• ambient unit-of-work aware outbox persistence for shared DatabaseContext scopes
• optional background retention cleanup for inbox/outbox tables

What it does not contain

• broker-specific Kafka client setup
• broker-specific RabbitMQ client setup
• EF Core entities for your application domain
• cross-resource distributed transactions

Usage

Example appsettings.json:

{
  "MessagingDatabasePersistenceConfiguration": {
    "InboxTableName": "messaging_inbox",
    "OutboxTableName": "messaging_outbox",
    "EnableCleanup": true,
    "CleanupInterval": "00:05:00",
    "CleanupBatchSize": 500,
    "ProcessedInboxRetention": "3.00:00:00",
    "DispatchedOutboxRetention": "3.00:00:00"
  }
}

builder.Services
    .AddRaycynixDatabase(builder.Configuration)
    .AddPostgreSql();

builder.Services.AddRaycynixMessaging(builder.Configuration)
    .AddDatabasePersistence(builder.Configuration);

You can still override specific values in code:

builder.Services.AddRaycynixMessaging(builder.Configuration)
    .AddDatabasePersistence(builder.Configuration, options =>
    {
        options.InboxTableName = "tenant_a_messaging_inbox";
    });

The package replaces the default in-memory inbox/outbox stores with database-backed implementations and registers its EF Core configurators into the shared DatabaseContext through AddRaycynixDatabaseAssembly(...). Table creation still flows through the existing Raycynix database initialization pipeline.

Inbox and outbox lease acquisition uses optimistic concurrency through EF Core model metadata, so the package stays provider-agnostic across SQLite, PostgreSQL, SQL Server, and MySQL without introducing provider-specific SQL into the messaging layer.

This package gives messaging persistence that survives process restarts, participates in the ambient shared DatabaseContext unit of work for outbox writes, runs retention cleanup, and works with the existing outbox recovery pipeline. It does not provide distributed transactions, but it does provide durable inbox/outbox state and database-backed recovery and dispatch leasing in the configured relational database.
