I want to customize ElasticSearch to include a cluster-wide state (for example a counter, readable via \_cluster/state) so that my ES plugin or other process can take actions based on that? How can the node publish that state which will ultimately be synchronized by master node to all data nodes?

How much data will need to be held? How frequently is it likely to get updated?
