Examples of voldemort.routing.RoutingStrategy

voldemort.routing.RoutingStrategy
A routing strategy maps puts and gets to an ordered "preference list" of servers. The preference list is the order under which operations will be completed in the absence of failures.

        // acquire read lock
        readLock.lock();
        try {
            Map<String, RoutingStrategy> routingStrategyMap = (Map<String, RoutingStrategy>) metadataCache.get(ROUTING_STRATEGY_KEY)
                                                                                                          .getValue();
            RoutingStrategy strategy = routingStrategyMap.get(storeName);
            if(strategy == null) {
                Map<String, RoutingStrategy> systemRoutingStrategyMap = (Map<String, RoutingStrategy>) metadataCache.get(SYSTEM_ROUTING_STRATEGY_KEY)
                                                                                                                    .getValue();
