Apache Distributed Cache refers to caching solutions provided by the Apache Foundation, which include Apache Ignite and Apache Geode. These are memory-centric platforms used for transactional, analytical, and caching workloads enabling in-memory speed and massive scalability.
Here's a basic guide on setting up Apache Ignite as an example of Apache Distributed Cache.
You can extract the Apache Ignite binary using the following command
tar -xvf apache-ignite-fabric-2.8.1-bin.zip
This will create a directory named apache-ignite-{version}-bin
.
Navigate to the bin
directory inside the extracted folder and execute the ignite.sh
(for Linux/Mac) or ignite.bat
(for Windows) script.
cd apache-ignite-fabric-2.8.1-bin/bin ./ignite.sh
Once you execute the script, an Ignite node will get started.
To use Ignite as a distributed cache, you need to configure the cache first. Here is an example of a simple cache configuration:
IgniteConfiguration cfg = new IgniteConfiguration(); // Create a new cache configuration. CacheConfiguration<Integer, String> cacheCfg = new CacheConfiguration<>("myCache"); // Configure the cache. cacheCfg.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL); cacheCfg.setBackups(1); cfg.setCacheConfiguration(cacheCfg);
After the cache configuration, you can use Ignite's cache API to interact with the distributed cache:
Ignite ignite = Ignition.start(cfg); // Get the instance of the configured cache. IgniteCache<Integer, String> cache = ignite.getOrCreateCache("myCache"); // Perform operations on the cache. cache.put(1, "Hello"); System.out.println("Value for 1: " + cache.get(1));
Please note that this is a simplified version of the setup process. For production environments, more complex configurations might be necessary.
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
