Needing more performance from your Java applications? Is latency causing you stress? Repetitive loading of the data in applications, burning CPU time, taxing I/O / disk access? Too many applications caching the same data sets pushing the limits of your data management and application architecture? If so, take a look at JCache! This code-driven session demonstrates how to integrate Hazelcast Distributed Caches into your Spring or Java EE applications. Adding a bunch of annotations to a method can achieve an orders-of-magnitude speed improvement in applications with high-latency.

3. •Performance
• Offload expensive parts of your architecture
•Scale up – get the most out of one machine
• Scale out – add more capacity with more machines
• Usually very fast and easy to apply
Cache is good for…

3. Embrace the standards – Enable JCache
import javax.cache.annotation.CacheResult;
import org.springframework.cache.annotation.EnableCaching;
@SpringBootApplication
@EnableCaching
public class SpringwebinarApplication {
public static interface CityService {
@CacheResult(cacheName = "city")
public String getCity();
}
@Bean
public CityService getService() {
return new CityService() {
@Override public String getCity() {
// slow code goes here!
return result;
}
};
}
}
