K - keyV - valuepublic class RedissonMapCache<K,V> extends RedissonMap<K,V> implements RMapCache<K,V>
Map-based cache with ability to set TTL for each entry via
put(Object, Object, long, TimeUnit) or putIfAbsent(Object, Object, long, TimeUnit) methods.
And therefore has an complex lua-scripts inside.
Current redis implementation doesnt have map entry eviction functionality.
Thus entries are checked for TTL expiration during any key/value/entry read operation.
If key/value/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 RedissonMapReactive.
