Hi Steve,
In your code, you can use the Cellar Hazelcast instance (exposed as a service).
Then, you can store the data (shared between Cellar nodes) using a distributed
list (or map or set). NB: the class you put in the distributed resources has to
implement Serializable.
For instance:
ServiceReference ref =
bundleContext.getServiceReference(HazelcastInstance.class);
HazelcastInstance cellar = bundleContext.getService(ref);
List distributedList = cellar.getList("name");
// add an element to the list
distributedList.add(new MySerializableClass());
// it's available on the other nodes
Cellar uses this internally to store the state of the features, bundles, config,
DOSGi, etc.
Regards
JB

Is there a way for instances within a Cellar cluster to communicate with each
other and exchange data? I’d like to be able to associate objects with specific
instances but still allow other instances to retrieve objects via other
instances in the cluster.
