SourceFlow.Net applications to the cloud with AWS or Azure, idempotency is crucial for handling duplicate messages in distributed systems. + +#### Single-Instance Deployments (Default) + +For single-instance deployments, SourceFlow automatically uses an in-memory idempotency service: + +```csharp +services.UseSourceFlow(); + +services.UseSourceFlowAws( + options => { options.Region = RegionEndpoint.USEast1; }, + bus => bus + .Send.Command(q => q.Queue("orders.fifo")) + .Listen.To.CommandQueue("orders.fifo")); +``` + +#### Multi-Instance Deployments (Recommended for Production) + +For multi-instance deployments, use the SQL-based idempotency service to ensure duplicate detection across all instances: + +```csharp +services.UseSourceFlow(); + +// Register Entity Framework stores with SQL-based idempotency +services.AddSourceFlowEfStores(connectionString); +services.AddSourceFlowIdempotency( + connectionString: connectionString, + cleanupIntervalMinutes: 60); + +// Configure cloud integration (AWS or Azure) +services.UseSourceFlowAws( + options => { options.Region = RegionEndpoint.USEast1; }, + bus => bus + .Send.Command(q => q.Queue("orders.fifo")) + .Listen.To.CommandQueue("orders.fifo")); +``` + +**Benefits of SQL-Based Idempotency:** +- ✅ Distributed duplicate detection across multiple instances +- ✅ Automatic cleanup of expired records +- ✅ Database-backed persistence for reliability +- ✅ Supports SQL Server, PostgreSQL, MySQL, SQLite + +For more details, see: +- [AWS Cloud Integration](src/SourceFlow.Cloud.AWS/README.md) +- [Azure Cloud

+SourceFlow.Net includes built-in resilience patterns to handle transient failures and prevent cascading failures in distributed systems. + +#### Circuit Breaker Pattern + +The circuit breaker pattern prevents your application from repeatedly trying to execute operations that are likely to fail, allowing the system to recover gracefully. + +**Circuit Breaker States:** +- **Closed** - Normal operation, requests pass through +- **Open** - Failures exceeded threshold, requests fail immediately +- **Half-Open** - Testing if service has recovered + +**Configuration Example:** + +```csharp +using SourceFlow.Cloud.Resilience; + +services.AddSingleton(sp => +{ + var options = new CircuitBreakerOptions + { + FailureThreshold = 5, // Open after 5 failures + SuccessThreshold = 3, // Close after 3 successes in half-open + Timeout = TimeSpan.FromMinutes(1), // Wait 1 minute before half-open + SamplingDuration = TimeSpan.FromSeconds(30) // Failure rate window + }; + + return new CircuitBreaker(options); +}); +``` + +**Usage in Services:** + +```csharp +public class OrderService +{ + private readonly ICircuitBreaker _circuitBreaker; + + public OrderService(ICircuitBreaker circuitBreaker) + { + _circuitBreaker = circuitBreaker; + } + + public async Task ProcessOrderAsync(int orderId) + { + try + { + return await _circuitBreaker.ExecuteAsync(async () => + { + // Call external service that might fail + return await externalService.GetOrderAsync(orderId); + }); + } + catch (CircuitBreakerOpenException ex) + { + // Circuit is open, service is unavailable + _logger.LogWarning("Circuit breaker is open for order service: {Message}", ex.Message); + + // Return cached data or default response + return await GetCachedOrderAsync(orderId); + } + } +} +``` + +#### CircuitBreakerOpenException + +This exception is thrown when the circuit breaker is in the Open state and prevents execution of the requested operation. + +**Properties:** +- `Message` - Description of why the circuit is open +- `CircuitBreakerState` - Current state of the circuit breaker +- `OpenedAt` - Timestamp when the circuit opened +- `WillRetryAt` - Timestamp when the circuit

It simplifies the setup of message queues, topics, and subscriptions without dealing with low-level cloud service details. + +**Key Benefits:** +- **Type Safety** - Compile-time validation of command and event routing +- **Simplified Configuration** - Use short names instead of full URLs/ARNs +- **Automatic Resource Creation** - Queues, topics, and subscriptions created automatically +- **Intuitive API** - Natural, readable configuration with method chaining + +### Architecture + +The Bus Configuration System consists of three main components: + +```mermaid +graph TB + A[Application Startup] --> B[BusConfigurationBuilder] + B --> C[BusConfiguration] + C --> D[Bootstrapper] + D --> E{Resource Creation} + E -->|AWS| F[SQS Queues] + E -->|AWS| G[SNS Topics] + D --> J[Dispatcher Registration] + J --> K[Listener Startup] +``` + +1. **BusConfigurationBuilder** - Entry point for building routing configuration using fluent API +2. **BusConfiguration** - Holds the complete routing configuration for commands and events +3. **Bootstrapper** - Hosted service that creates cloud resources and initializes routing at startup + +### Quick Start + +Here's a minimal example configuring command and event routing: + +```csharp +using SourceFlow.Cloud.AWS; +using Amazon; + +public void ConfigureServices(IServiceCollection services) +{ + services.UseSourceFlowAws( + options => { + options.Region = RegionEndpoint.USEast1; + }, + bus => bus + .Send + .Command(q => q.Queue("orders.fifo")) + .Raise + .Event(t => t.Topic("order-events")) + .Listen.To + .CommandQueue("orders.fifo") + .Subscribe.To + .Topic("order-events")); +} +``` + +### Configuration Sections + +The fluent API is organized into four intuitive sections: + +#### Send - Command Routing + +Configure which commands are sent to which queues: + +```csharp +bus => bus + .Send + .Command(q => q.Queue("orders.fifo")) + .Command(q => q.Queue("orders.fifo")) + .Command(q => q.Queue("inventory.fifo")) +``` + +**Best Practices:** +- Group related commands to the same queue for ordering guarantees +- Use `.fifo` suffix for queues requiring ordered processing +- Use short queue names only (e.g., "orders.fifo", not full URLs) + +#### Raise - Event Publishing + +Configure which events are published to which topics: + +```csharp +bus => bus + .Raise + .Event(t => t.Topic("order-events")) + .Event(t => t.Topic("order-events")) + .Event(t => t.Topic("shipping-events")) +``` + +**Best Practices:** +- Group related events to the same topic for fan-out messaging +- Use descriptive topic names that reflect the event domain +- Use short topic names only (e.g., "order-events", not full ARNs) + +#### Listen - Command Queue Listeners + +Configure which command queues the application listens to: + +```csharp +bus => bus + .Listen.To + .CommandQueue("orders.fifo") + .CommandQueue("inventory.fifo") +``` + +**Note:** At least one command queue must be configured when subscribing to topics. + +#### Subscribe - Topic Subscriptions + +Configure which topics the application subscribes to: + +```csharp +bus => bus + .Subscribe.To + .Topic("order-events") + .Topic("payment-events") + .Topic("shipping-events") +``` + +**How it works:** The bootstrapper automatically creates subscriptions that forward topic messages to your configured command queues. + +### Complete Example + +Here's a realistic scenario combining all four sections: + +```csharp +using SourceFlow.Cloud.AWS; +using Amazon; + +public class Startup +{ + public void ConfigureServices(IServiceCollection services) + { + // Register SourceFlow core + services.UseSourceFlow(Assembly.GetExecutingAssembly()); + + // Configure AWS cloud integration with Bus Configuration System + services.UseSourceFlowAws( + options => { + options.Region = RegionEndpoint.USEast1; + options.EnableEncryption = true; + options.KmsKeyId = "alias/sourceflow-key"; + }, + bus => bus + // Configure command routing + .Send + .Command(q => q.Queue("orders.fifo")) + .Command(q => q.Queue("orders.fifo")) + .Command(q => q.Queue("orders.fifo")) + .Command(q => q.Queue("inventory.fifo")) + .Command(q => q.Queue("payments.fifo")) + + // Configure event publishing + .Raise + .Event(t => t.Topic("order-events")) + .Event(t => t.Topic("order-events")) + .Event(t => t.Topic("order-events")) + .Event(t => t.Topic("inventory-events")) + .Event(t => t.Topic("payment-events")) + + // Configure command queue listeners + .Listen.To + .CommandQueue("orders.fifo") + .CommandQueue("inventory.fifo") + .CommandQueue("payments.fifo") + + // Configure topic subscriptions + .Subscribe.To + .Topic("order-events") + .Topic("payment-events") + .Topic("inventory-events")); + } +} +``` + +### Bootstrapper Integration + +The bootstrapper is a hosted service that runs at application startup to initialize your cloud infrastructure: + +**What the Bootstrapper Does:** + +1. **Resolves Short Names** + - Converts short names to full SQS URLs and SNS ARNs + +2. **Creates Missing Resources** + - Creates queues with appropriate settings (FIFO attributes, sessions, etc.) + - Creates topics for event publishing + - Creates subscriptions that forward topic messages to command queues + +3. **Validates Configuration** + - Ensures at least one command queue exists when subscribing to topics + - Validates queue and topic names follow cloud provider conventions + - Checks for configuration conflicts + +4. **Registers Dispatchers** + - Registers command and event dispatchers with resolved routing + - Configures listeners to start polling queues + +**Execution Timing:** The bootstrapper runs before listeners start, ensuring all routing is ready before message processing begins. + +**Development vs. Production:** +- **Development**: Let the bootstrapper create resources automatically for rapid iteration +- **Production**: Use infrastructure-as-code (CloudFormation, Terraform, ARM templates) for controlled deployments + +### FIFO Queue Configuration + +Use the `.fifo` suffix to enable ordered message processing: + +**AWS (SQS FIFO Queues):** +```csharp +.Send + .Command(q => q.Queue("orders.fifo")) +``` +- Enables content-based deduplication +- Enables message grouping by entity ID +- Guarantees exactly-once processing + +### Best Practices + +1. **Command Routing Organization** + - Group related commands to the same queue for ordering + - Use separate queues for different bounded contexts + - Use FIFO queues when order matters + +2. **Event Routing Organization** + - Group related events to the same topic + - Use descriptive topic names reflecting the domain + - Design for fan-out to multiple subscribers + +3. **Queue and Topic Naming** + - Use lowercase with hyphens (e.g., "order-events") + - Use `.fifo` suffix for ordered processing + - Keep names short and descriptive + +4. **Resource Creation Strategy** + - Development: Use automatic creation for speed + - Staging: Mix of automatic and IaC + - Production: Use IaC for control and auditability + +5. **Testing** + - Unit test configuration without cloud services + - Integration test with LocalStack + - Validate routing configuration in tests + +### Troubleshooting + +**Issue: Commands not being routed** +- Verify command is configured in Send section +- Check queue name matches Listen configuration +- Ensure bootstrapper completed successfully + +**Issue: Events not being received** +- Verify event is configured in Raise section +- Check topic subscription is configured +- Ensure at least one command queue is configured + +**Issue: Resources not created** +- Check cloud provider credentials and permissions +- Verify bootstrapper logs for errors +- Ensure queue/topic names follow cloud provider conventions + +**Issue: FIFO ordering not working** +- Verify `.fifo` suffix is used in queue name +- Check entity ID is properly set in commands +- Ensure message grouping is configured + +### Cloud-Specific Documentation + +For detailed cloud-specific information: +- **AWS**: See [AWS Cloud Architecture](Architecture/07-AWS-Cloud-Architecture.md) +- **Testing**: See [Cloud Integration Testing](Cloud-Integration-Testing.md) + --- ## 🗂️ Persistence Options diff --git a/docs/SourceFlow.Stores.EntityFramework-README.md b/docs/SourceFlow.Stores.EntityFramework-README.md index c45482b..1ad52d7 100644 --- a/docs/SourceFlow.Stores.EntityFramework-README.md +++ b/docs/SourceFlow.Stores.EntityFramework-README.md @@ -5,6 +5,7 @@ Entity Framework Core persistence provider for SourceFlow.Net with support for S ## Features -

Verifies event delivery to all subscribers with proper fan-out messaging +4. ✅ **SNS Message Filtering and Error Handling** - Tests subscription filters and error handling mechanisms +5. ✅ **KMS Encryption Round-Trip Consistency** - Ensures message encryption and decryption correctness with the following validations: + - Round-trip consistency: decrypt(encrypt(plaintext)) == plaintext + - Encryption non-determinism: same plaintext produces different ciphertext each time + - Sensitive data protection: plaintext substrings not visible in ciphertext + - Performance characteristics: encryption/decryption within reasonable time bounds + - Unicode safety: proper handling of multi-byte characters + - Base64 encoding: ciphertext properly encoded for transmission +6. ✅ **KMS Key Rotation Seamlessness** - Validates seamless key rotation without service interruption + - Messages encrypted with old keys decrypt after rotation + - Backward compatibility with previous key versions + - Automatic key version management + - Rotation monitoring and alerting +7. ✅ **KMS Security and Performance** - Tests sensitive data masking and performance characteristics + - [SensitiveData] attributes properly masked in logs + - Encryption performance within acceptable bounds + - IAM permission enforcement + - Audit logging and compliance +8. ✅ **AWS Health Check Accuracy** - Verifies health checks accurately reflect service availability + - Health checks detect service availability, accessibility, and permissions + - Health checks complete within acceptable latency (< 5 seconds) + - Reliability under concurrent access (90%+ consistency) + - SQS queue existence, accessibility, send/receive permissions + - SNS topic availability, attributes, publish permissions, subscription status + -
