@lancerdima you need to bind a instance of caffeine cache into Camel Registry
```
import org.apache.camel.BindToRegistry;
import org.apache.camel.builder.RouteBuilder;
import com.github.benmanes.caffeine.cache.Cache;
import com.github.benmanes.caffeine.cache.Caffeine;
public class CacheTest extends RouteBuilder {
@BindToRegistry
public static Cache<String, Object> cache() {
return Caffeine.newBuilder()
.build();
}
@Override
public void configure() throws Exception {
from("timer:offsetHandler?fixedRate=true&period=10000&delay=5000")
.to("caffeine-cache:cache?key=offset&action=GET")
.log("Old value: ${body}")
.setBody(simple("${headers.CamelTimerCounter}"))
.to("caffeine-cache:cache?action=PUT&key=offset")
.log("New value: ${body}");
}
}
```
Then the result will be what you expect:
```
