Class AsyncStore

java.lang.Object
  org.infinispan.loader.decorators.AbstractDelegatingStore
      org.infinispan.loader.decorators.AsyncStore

All Implemented Interfaces:

CacheLoader, CacheStore

public class AsyncStore
extends AbstractDelegatingStore

The AsyncStore is a delegating CacheStore that extends AbstractDelegatingStore, overriding methods to that should not just delegate the operation to the underlying store.

Read operations are done synchronously, while write operations are done asynchronously. There is no provision for exception handling for problems encountered with the underlying store during a write operation, and the exception is just logged.

When configuring the loader, use the following element:

<async enabled="true" />

to define whether cache loader operations are to be asynchronous. If not specified, a cache loader operation is assumed synchronous and this decorator is not applied.

Since:

4.0
