com.fasterxml.clustermate.service.bdb.NodeStateStore
Class that handles operations on the BDB-backed Node state table (BDB database) and related indexes. This store is used for persisting enough state regarding peer-to-peer operations to reduce amount of re-synchronization needed when node instances are restarted.

         * local DB. If we do, we may be able to avoid syncing from
