namastack/namastack-outbox

This system is a Spring Boot library that implements the outbox pattern to ensure reliable, transactional event publishing to external message brokers. It provides a comprehensive processing pipeline that supports typed and generic handlers, configurable retry policies, and fallback mechanisms for failed records. The framework includes built-in support for multiple database backends (JDBC, JPA, MongoDB) and integrations with Kafka, RabbitMQ, and AWS SNS. Additionally, it features distributed coordination for horizontal scaling, adaptive polling, and end-to-end observability via Micrometer and OpenTelemetry.

This period focused on rebuilding the outbox core with a new handler registry, retry policies, and instance coordination, while removing legacy implementations. The team also added comprehensive documentation, demo applications, and integration tests to validate the new architecture.
