What's Cooking Inside AxonIQ's Kitchen - Our 2025 Outlook

AxonIQ isn’t here to play by the old rules—we’re here to rewrite them. Welcome to the latest deep dive into our world of making event sourcing easy, where we challenge assumptions and push boundaries with Axon Framework, Axon Server, and the radical shift that is Dynamic Consistency Boundaries (DCB).

Killing the Aggregate: What’s the Deal with DCB?

Forget what you thought you knew about aggregates. Dynamic Consistency Boundaries (DCB) is shaking things up, getting rid of rigid aggregate boundaries and giving developers the power to work with a continuous stream of events, selecting only what matters when making decisions.

Traditionally, aggregates have defined consistency boundaries in event-driven architectures—but what if those boundaries are more of a constraint than a benefit? With DCB, event streams are no longer locked into predefined aggregate structures. Instead, developers can dynamically compose event-based state based on the needs of a given operation. This approach eliminates the need for predefined aggregate relationships and allows for more fluid, scalable, and maintainable systems.

By allowing for dynamic consistency boundaries, DCB ensures that business logic remains flexible, adapting to new insights over time rather than being permanently bound by initial modeling choices. It’s a seismic shift in how event sourcing is approached—one that removes many of the traditional pain points associated with aggregates while still maintaining the integrity of domain-driven decision-making.

Sound crazy? Maybe. But after years of refining and testing, we know this approach works—and it works well. It’s fast, backward-compatible, and, most importantly, liberating.

Axon Framework 5: Not Just an Upgrade—A Transformation

Here’s what’s coming:

• DCB Support: No more aggregate constraints—query events dynamically.

• Parallel Processing: Say goodbye to blocked threads and hello to efficiency.

• Reworked API Structure: More flexibility, less configuration headache.

• Smarter Snapshots: Solving snapshotting in a world without aggregates.

The best part? Existing applications won’t break. If you want to keep your aggregates, go for it. But for those ready to break free, DCB is here.

Axon Server & AxonIQ Console: Powering the Future of Event-Driven Systems

We’re not just changing the framework—we’re improving everything around it. Here’s what’s cooking:

Axon Server Updates:

• Scalability Enhancements: Optimized to support up to 900 connected applications efficiently.

• Next-Gen Indexing: A new lightweight index that improves memory efficiency and speeds up queries, especially for large installations.

• Spring Boot 3 & Spring Security 6 Migration: Reducing security vulnerabilities and improving compatibility with modern stacks.

• Performance Boosts: Improvements to handle large-scale event stores, ensuring responsiveness even with billions of aggregates.

AxonIQ Console Updates:

• A Sleek New UI: Dark mode, ultra-wide screen support, and a redesigned experience.

• Advanced Monitoring: New latency tracking that ensures stuck messages are visible and actionable.

• Expanded Integration Options: New notification features for Slack, PagerDuty, webhooks, and email alerts.

• Rapid-Fire Releases: 142 updates last year alone—because waiting around isn’t our style.

What’s Next?

The first iteration of DCB is expected to land early summer—solid, functional, and ready for action. AxonIQ Console will keep evolving, getting smarter, faster, and more intuitive. And if you’re wondering about AxonIQ Conference 2024, set aside late September. No announcement on a date just yet – but it’s happening, and it’s going to be big. 

AxonIQ is here to make event sourcing easier, bolder, and more powerful. With DCB, Axon Framework 5, and a relentless drive to innovate, we’re tearing down old constraints and giving developers the tools to build the future. The only question is: are you ready?
