Axon Server 2025.2.0

We have released a new version of the Axon Server.

New Features:

  • Analytics nodes to support SQL and natural language queries on event data:
    • Dedicated node for running analytics workloads
    • Improved performance and scalability for analytics tasks
    • Insights agent for LLM integrations
    • MCP support for analytics nodes
  • Full support for Dynamic Consistency Boundaries (DCB) including event re-tagging capabilities:
    • Add new tags to existing events without modification of event data
    • Remove existing tags from events as needed
  • Snapshot support for DCB contexts
  • Backup/restore support for DCB contexts
  • UI improvements:
    • List view for the topology overview page
  • Updated Docker base image

Note: DCB contexts created with the beta feature in 2025.1.0 will require you to remove a file rainbow.lsi prior to upgrading, as it’s defaults have changed. This only affects DCB contexts.

  • axoniq.axonserver.analytics.eventlake.enabled: Enable analytics processing on the node (default: false)
  • axoniq.axonserver.ai.mcp: Enable the AI MCP server on the node (default: false)
