Interface Storage

All Superinterfaces:

ReplicationStorage

All Known Implementing Classes:

StorageMemory

public interface Storage
extends ReplicationStorage

The storage is typically backed by multiple Java collections (HashMap, TreeMap, etc.). This map returns the map that stores the values which are present in the DHT. If you plan to do transactions (put/get), make sure you do the locking in order to not interfere with other threads that use this map. Although the storage is threadsafe, there may be concurrency issues with respect to transactions (e.g., do a get before a put). Please use StorageLayer.getLockStorage() for full locking, and StorageLayer.getLockNumber160(), StorageLayer.getLockNumber320(), StorageLayer.getLockNumber480(), StorageLayer#getLockNumber640() for fine grained locking.
