K - keyV - valuepublic interface RMapCacheAsync<K,V> extends RMapAsync<K,V>
Async interface for map-based cache with ability to set TTL for each entry via {RMapCacheAsync#putAsync(K, V, long, TimeUnit)} or {RMapCacheAsync#putIfAbsentAsync(K, V, long, TimeUnit)} And therefore has an complex lua-scripts inside.
Current redis implementation doesnt have 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.

Stores value mapped by key with specified time to live. Entry expires after specified time to live. If the map previously contained a mapping for the key, the old value is replaced by the specified value.

Stores value mapped by key with specified time to live and max idle time. Entry expires when specified time to live or max idle time has expired.
If the map previously contained a mapping for the key, the old value is replaced by the specified value.

RFuture<Boolean> fastPutAsync(K key, V value, long ttl, TimeUnit unit)
If the map previously contained a mapping for the key, the old value is replaced by the specified value.
Works faster than usual putAsync(Object, Object, long, TimeUnit)
as it not returns previous value.
