Class CacheEvictionsLogger

java.lang.Object
io.fluxzero.sdk.persisting.caching.CacheEvictionsLogger
All Implemented Interfaces:
Consumer<io.fluxzero.common.caching.CacheEviction>
public class CacheEvictionsLogger extends Object implements Consumer<io.fluxzero.common.caching.CacheEviction>
Logs and publishes cache eviction events as metrics.

This class listens for eviction events from a Cache and forwards them to the configured MetricsGateway. It is typically used to track cache performance and health over time, especially in distributed or memory-sensitive applications.

To activate logging for a particular cache instance, call register(Cache). This will subscribe the logger to that cache’s eviction stream. 


Cache cache = ...;
CacheEvictionsLogger logger = new CacheEvictionsLogger(Fluxzero.get().metricsGateway());
logger.register(cache);
