Release Notes - Karaf Cellar - Version 2.2.5

This release of Apache Karaf Cellar is based off of the 2.2.x series branch, representing a major update to Apache Karaf Cellar 2.2.4. It contains bug fixes
identified in the prior release, and introduces new features.

Cellar is a clustering solution for Apache Karaf powered by Hazelcast.

Cellar allows you to manage a cluster of Karaf instances, providing synchronisation between instances.

Here is a short list of provided features:

  • Discovery: each Karaf Cellar node is discovered automatically by the others. You can use multicast or unicast for discovery.
  • Cluster group: a Karaf Cellar node could be part of one or more cluster group. Each Karaf unit (features, config, etc) is targeted to a group.
  • Distributed Configuration Admin: Karaf Cellar distributes the configuration data. The distribution is event-driven and filtered by cluster group.
  • Distributed Features Service: Karaf Cellar distributes the features and repositories information. It's also event-driven.

To install Cellar into your running Karaf instance, just install the Cellar feature:

karaf@root> features:addurl mvn:org.apache.karaf.cellar/apache-karaf-cellar/2.2.5/xml/features
