Guaranteed Reliability
Never lose a message: All records are saved together with your business data, ensuring that no important information is lost - even in the event of failures.
Effortless Scalability
Grow with your business: The system automatically distributes work across multiple application instances, so you can handle more load without manual intervention.
Flexible Integration
Easily connect to your business processes: Use simple, type-safe handlers to process any kind of event, command, or notification, tailored to your needs.
Automatic Error Handling
Reduce operational risk: Built-in retry and fallback mechanisms ensure that temporary issues are handled automatically, and critical failures are managed gracefully.
Full Observability
Gain insights and traceability: Context propagation and built-in metrics provide end-to-end visibility, making it easy to monitor, audit, and troubleshoot your event flows.
Seamless Operations
Works with your existing infrastructure: Supports all major databases and integrates smoothly with Spring Boot, so you can adopt it without disrupting your current systems.
How It Works
Namastack Outbox for Spring Boot brings bulletproof reliability to your event-driven systems - combining transactional integrity with seamless message delivery.
When your application writes data, both the entity table and the outbox table are updated within a single ACID transaction. This guarantees that your domain state and outgoing events remain consistent - even if the system crashes mid-operation.
A background outbox scheduler polls the database for new records and hands them off to your custom outbox processor - a lightweight interface you implement to publish messages to your broker (e.g. Kafka, RabbitMQ, SNS).
Once messages are successfully delivered, they’re marked as processed.
This architecture ensures:
- Zero message loss, even under failure
- Strict per-aggregate ordering for deterministic processing
- Horizontal scalability with hash-based partitioning
- At-least-once delivery with safe retry policies and observability
With Namastack Outbox for Spring Boot, you get the reliability of database transactions - and the resilience of message-driven design.
Build confidently. Scale safely. Never lose an event again.
