   ## time-to-live
   
  
positive.code: 
  Remove an entry from a region or remove a region from a cache.
  
  ## disk policy
  
  Determines whether LRU entries exceeding the entries limit for a caching region are destroyed or written to disk.
  
  ## distributed scope
  
  Enables a region to automatically send entry value updates to remote caches and incorporate updates received from remote caches. The scope identifies whether distribution operations must wait for acknowledgement from other caches before continuing. A distributed region's **cache loader** and **cache writer** (defined in the local cache) can be invoked for operations originating in remote caches.
  
negative.code: 
  User-implemented plug-in for receiving and handling region entry events. A region's cache listener is called after an entry in the local cache is modified.

  ## cache loader
  
  User-implemented plug-in for loading data into a region. A region's cache loader is used to load data that is requested of the region but is not available in the distributed system. For a distributed region, the loader that is used can be in a different cache from the one where the data-request operation originated. See also [cache writer](#nc_glossary_cache_writer) and [netSearch](#nc_glossary_netSearch).
  
  ## cache server
  
  A long-running, configurable caching process, generally used to serve cached data to the applications. Usually, cache servers are configured to operate as servers in a client-server typology and their regions are configured to be replicates. See also [server](#nc_glossary_server).
  
  <a id="nc_glossary_cache_writer"></a>
  
  ## cache writer
  
  User-implemented plug-in intended for synchronizing the cache with an outside data source. A region's cache writer is a synchronous listener to cache data events. The cache writer has the ability to abort a data modification. See also [cache loader](#nc_glossary_cache_loader).
