Remote Cache Aliases

What You Will Learn

How to add aliases to an existing remote cache so you can access the same cache data using alternative names.

Prerequisites

Java 17+
An Infinispan Server running on localhost:11222 (or Docker/Podman available for Testcontainers)

Step 1: Connect and Store Data

Connect to the server, obtain a remote cache, and store a value:

      // Connect to the server
      cacheManager = TutorialsConnectorHelper.connect();
      // Obtain the remote cache
      cache = cacheManager.getCache(TUTORIAL_CACHE_NAME);

      // Store a value
      cache.put("key", "value");
      // Retrieve the value and print it out
      System.out.printf("key = %s\n", cache.get("key"));

Step 2: Add and Use Aliases

Use the admin API to update the aliases configuration attribute. You can then access the same cache data through any of its aliases:

      // Add aliases to the cache
      cacheManager.administration().updateConfigurationAttribute(cache.getName(), "aliases", "alias alias2");

      // Retrieve the value through an alias
      cacheAlias = cacheManager.getCache("alias");
      if (cacheAlias != null) {
         System.out.printf("key = %s\n", cacheAlias.get("key"));
      }

The alias points to the same underlying cache, so all data is shared.

Step 3: Run the Tutorial

mvn package exec:java

You should see output like:

key = value
key = value
