如何确保我的 apache Ignite 2.x 分布式缓存放置是异步的

Question

下面我有一个使用 apache ignite 的分布式缓存示例。

我想在执行缓存放置操作时做到这一点：cache.put(i, new X12File("x12file" + i, LocalDateTime.now().toString()));它是完全异步的。这意味着我的放置操作应该非常快，并且推送到集群的其余部分应该在后台发生而不会给用户带来不便。我需要“即发即弃”功能。

我正在努力寻找文档中的异步选项。有人可以帮助我了解如何更改此代码以使我的看跌期权尽可能“即发即弃”吗？谢谢！

private static final String ORG_CACHE = IgniteCache.class.getSimpleName() + "Organizations";

public static void main(String[] args) throws Exception {
    DataRegionConfiguration dfltDataRegConf = new DataRegionConfiguration();
    dfltDataRegConf.setPersistenceEnabled(true);

    DataStorageConfiguration dsCfg = new DataStorageConfiguration();
    dsCfg.setDefaultDataRegionConfiguration(dfltDataRegConf);
    dsCfg.setStoragePath("/home/kazakov/tmp");

    IgniteConfiguration igniteConfiguration = new IgniteConfiguration();
    igniteConfiguration.setDataStorageConfiguration(dsCfg);

    TcpDiscoverySpi tcpDiscoverySpi = new TcpDiscoverySpi();
    TcpDiscoveryVmIpFinder ipFinder = new TcpDiscoveryVmIpFinder();
    ipFinder.setAddresses(Arrays.asList("127.0.0.1:47500..47509"));
    tcpDiscoverySpi.setIpFinder(ipFinder);

    igniteConfiguration.setDiscoverySpi(tcpDiscoverySpi);

    try(Ignite ignite = Ignition.start(igniteConfiguration)) {
        ignite.active(true);

        CacheConfiguration<Long, X12File> cacheCfg = new CacheConfiguration<>(ORG_CACHE);

        cacheCfg.setCacheMode(CacheMode.REPLICATED);
        cacheCfg.setAtomicityMode(CacheAtomicityMode.ATOMIC);
        cacheCfg.setBackups(1);
        cacheCfg.setOnheapCacheEnabled(true);

        IgniteCache<Long, X12File> cache = ignite.getOrCreateCache(cacheCfg).withExpiryPolicy(new CreatedExpiryPolicy(new Duration(TimeUnit.SECONDS, 1)));

        for (long i = 0; i < 4_000_000; i++) {
            if (i > 0 && i % 10_000 == 0)
                System.out.println("Done: " + i);

            cache.put(i, new X12File("x12file" + i, LocalDateTime.now().toString()));
        }

        Thread.sleep(5000);

        int matches = 0;
        for (long i = 0; i < 4_000_000; i++) {
            if (cache.get(i) != null)
                ++matches;
        }
        System.out.println("Matches: " + matches);
    }
}
