Interface RLocalCachedMap<K,V>

Type Parameters:

K - map key

V - map value

All Superinterfaces:

ConcurrentMap<K,V>, Map<K,V>, RDestroyable, RExpirable, RExpirableAsync, RMap<K,V>, RMapAsync<K,V>, RObject, RObjectAsync

All Known Implementing Classes:

RedissonLocalCachedMap, RedissonTransactionalLocalCachedMap

public interface RLocalCachedMap<K,V>
extends RMap<K,V>, RDestroyable

Map object with local entry cache support.

Each instance maintains local cache to achieve fast read operations. Suitable for maps which used mostly for read operations and network roundtrip delays are undesirable.

Method Detail

preloadCache

void preloadCache()

Pre-warm the cached values. Not guaranteed to load ALL values, but statistically will preload approximately all (all if no concurrent mutating activity) Intended for use with no-eviction caches where entire maps are locally cached

clearLocalCacheAsync

RFuture<Void> clearLocalCacheAsync()

Clears local cache across all instances

Returns:

void

clearLocalCache

void clearLocalCache()

Clears local cache across all instances

cachedKeySet

Set<K> cachedKeySet()

Returns all keys stored in local cache

Returns:

keys

cachedValues

Collection<V> cachedValues()

Returns all values stored in local cache

Returns:

values

cachedEntrySet

Set<Map.Entry<K,V>> cachedEntrySet()

Returns all map entries stored in local cache

Returns:

entries

getCachedMap

Map<K,V> getCachedMap()

Returns state of local cache

Returns:

map
