Hibernate Cache

Redisson implements Hibernate 2nd level Cache provider based on Redis.
All Hibernate cache strategies are supported: READ_ONLY, NONSTRICT_READ_WRITE, READ_WRITE and TRANSACTIONAL.

Compatible with Hibernate 4.x, 5.1.x, 5.2.x, 5.3.3+ up to 5.6.x and 6.0.2+ up to 6.x.x

Eviction, local cache and data partitioning

Redisson provides various Hibernate Cache factories including those with features below:

local cache - so called near cache, which is useful for use cases when Hibernate Cache used mostly for read operations and/or network roundtrips are undesirable. It caches Map entries on Redisson side and executes read operations up to 5x faster in comparison with common implementation. Local cache instances with the same name connected to the same pub/sub channel. This channel is used for exchanging of update/invalidate events between all instances. Cache store doesn't use hashCode()/equals() methods of key object, instead it uses hash of serialized state.

data partitioning - although all implementations are cluster compatible thier content isn't scaled/partitioned across multiple Redis or Valkey master nodes in cluster. Data partitioning allows to scale available memory, read/write operations and entry eviction process for individual Hibernate Cache instance in Redis or Valkey cluster.

1. Scripted eviction

Allows to define time to live or max idle time parameters per map entry. Eviction is done on Redisson side through a custom scheduled task which removes expired entries using Lua script. Eviction task is started once per unique object name at the moment of getting Map instance. If instance isn't used and has expired entries it should be get again to start the eviction process. This leads to extra Redis or Valkey calls and eviction task per unique map object name.

Entries are cleaned time to time by org.redisson.eviction.EvictionScheduler. By default, it removes 100 expired entries at a time. This can be changed through cleanUpKeysAmount setting. Task launch time tuned automatically and depends on expired entries amount deleted in previous time and varies between 5 second to 30 minutes by default. This time interval can be changed through minCleanUpDelay and maxCleanUpDelay. For example, if clean task deletes 100 entries each time it will be executed every 5 seconds (minimum execution delay). But if current expired entries amount is lower than previous one then execution delay will be increased by 1.5 times and decreased otherwise.

Usage

1. Add redisson-hibernate dependency into your project:

Maven

     <dependency>
         <groupId>org.redisson</groupId>
         <!-- for Hibernate v4.x -->
         <artifactId>redisson-hibernate-4</artifactId>
         <!-- for Hibernate v5.0.x - v5.1.x -->
         <artifactId>redisson-hibernate-5</artifactId>
         <!-- for Hibernate v5.2.x -->
         <artifactId>redisson-hibernate-52</artifactId>
         <!-- for Hibernate v5.3.3+ - v5.6.x -->
         <artifactId>redisson-hibernate-53</artifactId>
         <!-- for Hibernate v6.0.2+ - v6.x.x -->
         <artifactId>redisson-hibernate-6</artifactId>
         <version>xVERSIONx</version>
     </dependency>

Gradle

     // for Hibernate v4.x
     compile 'org.redisson:redisson-hibernate-4:xVERSIONx'
     // for Hibernate v5.0.x - v5.1.x
     compile 'org.redisson:redisson-hibernate-5:xVERSIONx'
     // for Hibernate v5.2.x
     compile 'org.redisson:redisson-hibernate-52:xVERSIONx'
     // for Hibernate v5.3.3+ - v5.6.x
     compile 'org.redisson:redisson-hibernate-53:xVERSIONx'
     // for Hibernate v6.0.2+ - v6.x.x
     compile 'org.redisson:redisson-hibernate-6:xVERSIONx'

2. Specify hibernate cache settings

Define Redisson Region Cache Factory:

<!-- Redisson Region Cache factory -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.RedissonRegionFactory" />
<!-- or -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.RedissonRegionV2Factory" />
<!-- or -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.RedissonLocalCachedRegionFactory" />
<!-- or -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.RedissonLocalCachedV2RegionFactory" />
<!-- or -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.RedissonClusteredRegionFactory" />
<!-- or -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.RedissonClusteredLocalCachedRegionFactory" />

By default each Region Factory creates own Redisson instance. For multiple applications, using the same Redis or Valkey setup and deployed in the same JVM, amount of Redisson instances could be reduced using JNDI registry:

<!-- name of Redisson instance registered in JNDI -->
<property name="hibernate.cache.redisson.jndi_name" value="redisson_instance" />

<!-- JNDI Redisson Region Cache factory -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.JndiRedissonRegionFactory" />
<!-- or -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.JndiRedissonRegionV2Factory" />
<!-- or -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.JndiRedissonLocalCachedRegionFactory" />
<!-- or -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.JndiRedissonLocalCachedV2RegionFactory" />
<!-- or -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.JndiRedissonClusteredRegionFactory" />
<!-- or -->
<property name="hibernate.cache.region.factory_class" value="org.redisson.hibernate.JndiRedissonClusteredLocalCachedRegionFactory" />

<!-- 2nd level cache activation -->
<property name="hibernate.cache.use_second_level_cache" value="true" />
<property name="hibernate.cache.use_query_cache" value="true" />

<!-- Redisson can fallback on database if Redis or Valkey cache is unavailable -->
<property name="hibernate.cache.redisson.fallback" value="true" />

<!-- Redisson YAML config (located in filesystem or classpath) -->
<property name="hibernate.cache.redisson.config" value="/redisson.yaml" />

JCache API (JSR-107)

Redisson provides an implementation of JCache API (JSR-107) for Redis.

Below are examples of JCache API usage.

1. Using default config located at /redisson-jcache.yaml:

// implementation with scripted eviction
MutableConfiguration<String, String> config = new MutableConfiguration<>();

// implementation with native eviction
NativeConfiguration<String, String> config = new NativeConfiguration<>();

// implementation with advanced eviction
V2Configuration<String, String> config = new V2Configuration<>();

        
CacheManager manager = Caching.getCachingProvider().getCacheManager();
Cache<String, String> cache = manager.createCache("namedCache", config);

2. Using config file with custom location:

// implementation with scripted eviction
MutableConfiguration<String, String> config = new MutableConfiguration<>();

// implementation with native eviction
NativeConfiguration<String, String> config = new NativeConfiguration<>();

// implementation with advanced eviction
V2Configuration<String, String> config = new V2Configuration<>();


// yaml config
URI redissonConfigUri = getClass().getResource("redisson-jcache.yaml").toURI();
CacheManager manager = Caching.getCachingProvider().getCacheManager(redissonConfigUri, null);
Cache<String, String> cache = manager.createCache("namedCache", config);

3. Using Redisson's config object:

// implementation with scripted eviction
MutableConfiguration<String, String> jcacheConfig = new MutableConfiguration<>();

// implementation with native eviction
NativeConfiguration<String, String> jcacheConfig = new NativeConfiguration<>();

// implementation with advanced eviction
V2Configuration<String, String> jcacheConfig = new V2Configuration<>();


Config redissonCfg = ...
Configuration<String, String> config = RedissonConfiguration.fromConfig(redissonCfg, jcacheConfig);

CacheManager manager = Caching.getCachingProvider().getCacheManager();
Cache<String, String> cache = manager.createCache("namedCache", config);

4. Using Redisson instance object:

// implementation with scripted eviction
MutableConfiguration<String, String> jcacheConfig = new MutableConfiguration<>();

// implementation with native eviction
NativeConfiguration<String, String> jcacheConfig = new NativeConfiguration<>();

// implementation with advanced eviction
V2Configuration<String, String> jcacheConfig = new V2Configuration<>();


RedissonClient redisson = ...
Configuration<String, String> config = RedissonConfiguration.fromInstance(redisson, jcacheConfig);

CacheManager manager = Caching.getCachingProvider().getCacheManager();
Cache<String, String> cache = manager.createCache("namedCache", config);

Read more here about Redisson configuration.

Provided implementation fully passes TCK tests. Here is the test module.

Asynchronous, Reactive and RxJava3 interfaces

Along with usual JCache API, Redisson provides Asynchronous, Reactive and RxJava3 API.

Asynchronous interface. Each method returns org.redisson.api.RFuture object.
Example:

// implementation with scripted eviction
MutableConfiguration<String, String> config = new MutableConfiguration<>();

// implementation with native eviction
NativeConfiguration<String, String> config = new NativeConfiguration<>();

// implementation with advanced eviction
V2Configuration<String, String> config = new V2Configuration<>();

        
CacheManager manager = Caching.getCachingProvider().getCacheManager();
Cache<String, String> cache = manager.createCache("myCache", config);

CacheAsync<String, String> asyncCache = cache.unwrap(CacheAsync.class);
RFuture<Void> putFuture = asyncCache.putAsync("1", "2");
RFuture<String> getFuture = asyncCache.getAsync("1");

Reactive interface. Each method returns reactor.core.publisher.Mono object.
Example:

// implementation with scripted eviction
MutableConfiguration<String, String> config = new MutableConfiguration<>();

// implementation with native eviction
NativeConfiguration<String, String> config = new NativeConfiguration<>();

// implementation with advanced eviction
V2Configuration<String, String> config = new V2Configuration<>();

        
CacheManager manager = Caching.getCachingProvider().getCacheManager();
Cache<String, String> cache = manager.createCache("myCache", config);

CacheReactive<String, String> reactiveCache = cache.unwrap(CacheReactive.class);
Mono<Void> putFuture = reactiveCache.put("1", "2");
Mono<String> getFuture = reactiveCache.get("1");

RxJava3 interface. Each method returns one of the following object: io.reactivex.Completable, io.reactivex.Single, io.reactivex.Maybe.
Example:

// implementation with scripted eviction
MutableConfiguration<String, String> config = new MutableConfiguration<>();

// implementation with native eviction
NativeConfiguration<String, String> config = new NativeConfiguration<>();

// implementation with advanced eviction
V2Configuration<String, String> config = new V2Configuration<>();

        
CacheManager manager = Caching.getCachingProvider().getCacheManager();
Cache<String, String> cache = manager.createCache("myCache", config);

CacheRx<String, String> rxCache = cache.unwrap(CacheRx.class);
Completable putFuture = rxCache.put("1", "2");
Maybe<String> getFuture = rxCache.get("1");

Local cache and data partitioning

Redisson provides JCache implementations with two important features:

local cache - so called near cache used to speed up read operations and avoid network roundtrips. It caches JCache entries on Redisson side and executes read operations up to 45x faster in comparison with common implementation. Local cache instances with the same name connected to the same pub/sub channel. This channel is used for exchanging of update/invalidate events between all instances. Local cache store doesn't use hashCode()/equals() methods of key object, instead it uses hash of serialized state.

data partitioning - although JCache instance is cluster compatible its content isn't scaled/partitioned across multiple Redis or Valkey master nodes in cluster. Data partitioning allows to scale available memory, read/write operations and entry eviction process for individual JCache instance in Redis or Valkey cluster.

fallback mode - if set to true and Redis or Valkey is down the errors won't be thrown allowing application continue to operate without Redis.

1. Scripted eviction

Eviction is done on Redisson side through a custom scheduled task which removes expired entries using Lua script. Eviction task is started once per unique cache name at the moment of getting JCache instance. If instance isn't used and has expired entries it should be get again to start the eviction process. This leads to extra Redis or Valkey calls and eviction task per unique cache name.

Available implementations:

	Local cache	Data partitioning	Ultra-fast read/write	Fallback mode
JCache _{open-source version}	❌	❌	❌	❌
JCache _{Redisson PRO version}	❌	❌	✔️	✔️
JCache with local cache _{available only in Redisson PRO}	✔️	❌	✔️	✔️
JCache with data partitioning _{available only in Redisson PRO}	❌	✔️	✔️	✔️
JCache with local cache and data partitioning _{available only in Redisson PRO}	✔️	✔️	✔️	✔️

2. Advanced eviction

Doesn't use an entry eviction task, entries are cleaned on Redis or Valkey side.

Available implementations:

	Local cache	Data partitioning	Ultra-fast read/write	Fallback mode
JCache V2 _{available only in Redisson PRO}	❌	✔️	✔️	✔️

3. Native eviction

Doesn't use an entry eviction task, entries are cleaned on Redis side.
Requires Redis 7.4+.

Available implementations:

	Local cache	Data partitioning	Ultra-fast read/write	Fallback mode
JCache native _{available only in Redisson PRO}	❌	❌	✔️	✔️
JCache native with data partitioning _{available only in Redisson PRO}	❌	✔️	✔️	✔️

Local cache configuration

      LocalCacheConfiguration<String, String> configuration = new LocalCacheConfiguration<>()

      // Defines whether to store a cache miss into the local cache.
      // Default value is false.
      .storeCacheMiss(false);

      // Defines store mode of cache data.
      // Follow options are available:
      // LOCALCACHE - store data in local cache only and use Redis or Valkey only for data update/invalidation.
      // LOCALCACHE_REDIS - store data in both Redis or Valkey and local cache.
      .storeMode(StoreMode.LOCALCACHE_REDIS)

      // Defines Cache provider used as local cache store.
      // Follow options are available:
      // REDISSON - uses Redisson own implementation
      // CAFFEINE - uses Caffeine implementation
      .cacheProvider(CacheProvider.REDISSON)

      // Defines local cache eviction policy.

MyBatis Cache

Redisson implements MyBatis Cache based on Redis.

Compatible with MyBatis 3.0.0+

Eviction, local cache and data partitioning

Redisson provides multiple MyBatis Cache implementations which support features below:

local cache - so called near cache used to speed up read operations and avoid network roundtrips. It caches Map entries on Redisson side and executes read operations up to 45x faster in comparison with common implementation. Local cache instances with the same name connected to the same pub/sub channel. This channel is used for exchanging of update/invalidate events between all instances. Local cache store doesn't use hashCode()/equals() methods of key object, instead it uses hash of serialized state.

data partitioning - although Map object is cluster compatible its content isn't scaled/partitioned across multiple Redis or Valkey master nodes in cluster. Data partitioning allows to scale available memory, read/write operations and entry eviction process for individual Map instance in Redis or Valkey cluster.

1. Scripted eviction

Allows to define time to live or max idle time parameters per entry. Eviction is done on Redisson side through a custom scheduled task which removes expired entries using Lua script. Eviction task is started once per unique object name at the moment of getting Map instance. If instance isn't used and has expired entries it should be get again to start the eviction process. This leads to extra Redis or Valkey calls and eviction task per unique map object name.

maxSize - defines max size of entries amount stored in Redis

localCacheProvider - cache provider used as local cache store. REDISSON and CAFFEINE providers are available. Default value: REDISSON

localCacheEvictionPolicy - local cache eviction policy. LFU, LRU, SOFT, WEAK and NONE eviction policies are available.

localCacheSize - local cache size. If size is 0 then local cache is unbounded.

localCacheTimeToLive - time to live in milliseconds for each map entry in local cache. If value equals to 0 then timeout is not applied.

localCacheMaxIdleTime - max idle time in milliseconds for each map entry in local cache. If value equals to 0 then timeout is not applied.

localCacheSyncStrategy - local cache sync strategy. INVALIDATE, UPDATE and NONE eviction policies are available.

redissonConfig - defines path to redisson config in YAML format

quarkus.cache.redisson.[CACHE_NAME].reconnection-strategy - used to load missed updates during any connection failures to Redis. Default value isCLEAR. Since, local cache updates can't be executed in absence of connection to Redis. Available values:
- CLEAR - Clear local cache if map instance has been disconnected for a while.
- LOAD - Store invalidated entry hash in invalidation log for 10 minutes. Cache keys for stored invalidated entry hashes will be removed if LocalCachedMap instance has been disconnected less than 10 minutes or whole cache will be cleaned otherwise.
- NONE - No reconnection handling

redisson.cache.redisson.[CACHE_NAME].eviction-policy - defines local cache eviction policy. Default value isNONE. Available values:
- LRU - uses local cache with LRU (least recently used) eviction policy.
- LFU - uses local cache with LFU (least frequently used) eviction policy.
- SOFT - uses local cache with soft references. The garbage collector will evict items from the local cache when the JVM is running out of memory.
- WEAK - uses local cache with weak references. The garbage collector will evict items from the local cache when it became weakly reachable.
- NONE - doesn't use eviction policy, but timeToLive and maxIdleTime params are still working.
redisson.cache.redisson.[CACHE_NAME].time-to-live - time to live duration of each map entry in local cache. If value equals to 0 then timeout is not applied. Default value is 0.

redisson.cache.redisson.[CACHE_NAME].max-idle - defines max idle time duration of each map entry in local cache. If value equals to 0 then timeout is not applied. Default value is 0.

redisson.cache.redisson.[CACHE_NAME].store-mode - defines store mode of cache data. Default value is LOCALCACHE_REDIS. Available values:
- LOCALCACHE - store data in local cache only and use Redis or Valkey only for data update/invalidation
- LOCALCACHE_REDIS - store data in both Redis or Valkey and local cache
