Usage is very similar to the normal put and get methods except that each method returns a Future instead of the object.

putAsync

Returns immediately and puts the object into the cache in a background thread.

bigcache.putAsync(key, object, expiresInSeconds);

If a problem occurred while putting the object, you might not notice since it happened in the background. In the case where you need to know, you can use:

Future future = bigcache.putAsync(key, object, expiresInSeconds);
...
// You can call future.get() later to see if any exception was thrown

getAsync

Gets an object from the cache in the background.

Future future = getAsync(String key);
...
// sometime in the future
MyObject myObject = future.get();

Useful in various scenarios, but one in particular is for getting objects in a webapp before rendering the view. When rendering the view, you then call get() on the Future.
