Java 8 has reached end of support and will be deprecated on January 31, 2026. After deprecation, you won't be able to deploy Java 8 applications, even if your organization previously used an organization policy to re-enable deployments of legacy runtimes. Your existing Java 8 applications will continue to run and receive traffic after their deprecation date. We recommend that you migrate to the latest supported version of Java.

AsyncMemcacheService (Google App Engine API for Java)

All Superinterfaces:

BaseMemcacheService
```
public interface AsyncMemcacheService
extends BaseMemcacheService
```
An asynchronous version of MemcacheService. All methods return immediately and provide Futures as their return values.
