Implements [MyBatis Cache](https://mybatis.org/mybatis-3/sqlmap-xml.html#cache) provider based on Redis.
Compatible with MyBatis 3.0.0+
Redisson provides various MyBatis Cache implementations 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. All local caches with the same name connected to the same pub/sub channel which is used for messaging between them. In particular to send entity update or entity invalidate event.
**data partitioning** - data partitioning in cluster mode. It allows to scale available memory, read/write operations and entry eviction process for individual Hibernate Cache instance in Redis cluster.
Below is the list of all available implementations with local cache and/or data partitioning support:
|Class name | Local cache <br/> support<br/>(up to 5x faster) | Data partitioning <br/> support |
| ------------- | ------------- | ------------|
|RedissonCache<br/> | No | No |
|RedissonLocalCachedCache<br/><sub><i>available only in [Redisson PRO](http://redisson.pro) edition</i></sub> | **Yes** | No |
|RedissonClusteredCache<br/><sub><i>available only in [Redisson PRO](http://redisson.pro) edition</i></sub> | No | **Yes** |
|RedissonClusteredLocalCachedCache<br/><sub><i>available only in [Redisson PRO](http://redisson.pro) edition</i></sub> | **Yes** | **Yes** |
## Hibernate Cache Usage
### 1. Add `redisson-mybatis` dependency into your project:
Maven
```xml
<dependency>
<groupId>org.redisson</groupId>
<artifactId>redisson-mybatis</artifactId>
<version>3.11.7</version>
</dependency>
```
Gradle
```groovy
compile 'org.redisson:redisson-mybatis:3.11.7'
```
### 2. Specify MyBatis cache settings
Redisson allows to define follow settings per Cache instance:
`timeToLive` - defines time to live per cache entry
`maxIdleTime` - defines max idle time per cache entry
`maxSize` - defines max size of entries amount stored in Redis
`redissonConfig` - defines path to redisson config in YAML format
