Axoniq and Apache Kafka

Turn Event Streams into
Auditable, Historical Storage.

Turn Event Streams into Auditable, Historical Storage.

Upgrade your Apache Kafka® streams into a compliant, AI-ready source of truth. Axoniq provides the persistent historical storage layer your event streaming architecture requires.

Integrate Kafka with Axoniq

Read the Architecture Guide

From open source to enterprise, Axoniq powers mission-critical software across global organizations.

The Missing Half of Your Event-Driven Strategy

You rely on Apache Kafka for high-throughput event streaming. It is the undisputed leader in moving data from A to B. But in regulated industries and complex systems, moving data isn't enough—you need to retain the context and prove why the data moved.

Kafka acts as the messenger. Axoniq acts as the historical ledger.

By combining Kafka’s distribution power (Event Streaming) with Axoniq’s purpose-built Historical Storage and event sourcing persistence, you create an architecture that is not just fast, but intelligent, auditable, and ready for the next generation of AI.

Why Kafka and Axoniq Are Better Together

Apache Kafka

The Event Streaming Messenger

Axoniq

The Persistent Historical Storage

Focus

High-velocity event streaming and distribution.

Event sourcing, historical storage, and state management

Retention

Ephemeral. Events are typically deleted after a set window.

Permanent. A complete, immutable history of every business decision.

Role

Transports data between microservices.

The Single Source of Truth for state reconstruction and causality.

AI capability

Feeds real-time data to models.

Provides the causal lineage required for AI Explainability.

From Event Streaming to AI-Ready Historical Storage

The shift to Artificial Intelligence requires more than just streaming data; it requires historical storage for context. Current event streaming architecture often fails to explain why an AI model made a specific decision, creating a massive compliance gap.

Axoniq provides the AI event sourcing infrastructure and historical storage that:

Guarantees Auditability

Reconstruct any system state from any point in time

Seamless Integration

You don't need to rip and replace. The Axoniq Kafka Extension bridges the gap between event streaming and historical storage.

CQRS Implementation

Use Kafka as your distribution bus while Axon Server handles the dedicated Historical Storage for Command Query Responsibility Separation (CQRS).
