public class RedissonSetCache<V> extends RedissonObject implements RSetCache<V>, ScanIterator

Set-based cache with ability to set TTL for each entry via RSetCache.add(Object, long, TimeUnit) method.

Current Redis implementation doesn't have set entry eviction functionality. Thus values are checked for TTL expiration during any value read operation. If entry expired then it doesn't returns and clean task runs asynchronous. Clean task deletes removes 100 expired entries at once. In addition there is EvictionScheduler. This scheduler deletes expired entries in time interval between 5 seconds to 2 hours.

If eviction is not required then it's better to use RSet.
