= Apache Ignite as MyBatis L2 Cache

Apache Ignite can be used as a MyBatis L2 cache that distributes and caches data across a cluster of machines.

If you are an Apache Maven user, simply add the following dependency to the `pom.xml`:

[tabs]
--
tab:pom.xml[]
[source,xml]
----
<dependencies>
  ...
  <dependency>
    <groupId>org.mybatis.caches</groupId>
    <artifactId>mybatis-ignite</artifactId>
    <version>1.0.5</version>
  </dependency>
  ...
</dependencies>
----
--

Alternatively, you can also download the https://github.com/mybatis/ignite-cache/releases[zip bundle, window=_blank],
decompress it and add the jars in the classpath.

Then, just specify it in the mapper XML as follows:

[tabs]
--
tab:XML[]
[source,xml]
----
<mapper namespace="org.acme.FooMapper">
  <cache type="org.mybatis.caches.ignite.IgniteCacheAdapter" />
</mapper>
----
--

and configure your Ignite cache in `config/default-config.xml`. (Simple reference configurations are available on
https://github.com/mybatis/ignite-cache/tree/master/config[GitHub, window=_blank])
