AxonIQ/AxonFramework

This system is a comprehensive distributed application framework for building event-driven, event-sourced architectures. It provides a modular infrastructure for handling commands, queries, and events, featuring a robust conversion layer for serializing and deserializing messages across various formats like JSON, Avro, and CBOR. The framework supports advanced event sourcing patterns, including entity lifecycle management, snapshotting, and flexible storage backends such as JPA, JDBC, and in-memory stores. Additionally, it offers extensive tooling for monitoring, tracing, and security, with deep integration into the Spring Boot ecosystem for rapid development and configuration.

This period encompasses the development of the Axon Framework 5.0 release, featuring a comprehensive architectural overhaul of the messaging, event sourcing, and query handling subsystems. It also includes the introduction of a new Spring Boot integration layer, extensive test coverage for the new components, and an automated migration tool to upgrade applications from version 4.x.

This period focused on deepening Spring Boot auto-configuration for metrics and testing, while introducing Reactor-based gateways and a new snapshotting API for event sourcing. The team also expanded the framework's messaging capabilities with new sequencing policies, JPA transaction management, and annotation-based interceptors for commands, events, and queries.
