cache2k is an in-memory high performance Java Caching library.

  Cache<String,String> cache = new Cache2kBuilder<String, String>() {}
    .expireAfterWrite(5, TimeUnit.MINUTES)    // expire/refresh after 5 minutes
    .setupWith(UniversalResiliencePolicy::enable, b -> b // enable resilience policy
      .resilienceDuration(30, TimeUnit.SECONDS)          // cope with at most 30 seconds
                                                         // outage before propagating 
                                                         // exceptions
    )
    .refreshAhead(true)                       // keep fresh when expiring
    .loader(this::expensiveOperation)         // auto populating function
    .build();
