Release Notes - Karaf Cellar - Version 2.2.3
This is the first release of Karaf Cellar.
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:
