Contents and Example Usage

org.gfccollective.cache.AsyncCache & AsyncCacheImpl

AsyncCache represents an asynchronous cache. It may not contain the whole data, and will return Future[Option[V]] to show that the value may be lazy-loaded by issuing a remote call.

AsyncCacheImpl is an implementation of AsyncCache that adds build-load functionality, which requires a load function to be implemented, which is called on cache-miss.

org.gfccollective.cache.SyncCache & SyncCacheImpl

SyncCache represents an in-memory cache, returning values as Option[V] indicating that no values are lazy-loaded on cache-miss.

SyncCacheImpl is an implementation of SyncCache that adds build-load functionality, which requires a load function to be implemented, which is called on cache-miss.

org.gfccollective.cache.CacheConfiguration

Mix in this trait to provide configuration for the cache. The following parameters are needed:

• refreshPeriodMs: how often to reload the cache, in millis.
• cacheInitStrategy: how to initialize the cache, either synchronously or asynchronously.
