java - 点燃持久化集合：找不到具有紧凑页脚的对象的元数据

问题描述

我正在尝试为模型集创建具有持久性的 Ignite 缓存。即，IgniteCache<String, Set<Model>>。

在本地运行时，一切正常。我可以重新启动应用程序并 Ignite 加载它的持久数据库。

但是当使用 Docker 或 Kubernetes 运行时（使用挂载的卷以实现持久性），我无法重新启动应用程序。否则我会收到此错误：

我创建了一个 GitHub 存储库以方便测试... https://github.com/jesjobom/ignite-persistence-test/

主要配置：

System.setProperty(IgniteSystemProperties.IGNITE_NO_SHUTDOWN_HOOK, "true");

IgniteConfiguration igniteConfiguration = new IgniteConfiguration();

//Region for persistent (in disk) data
DataRegionConfiguration persistence = new DataRegionConfiguration().setPersistenceEnabled(true)
        .setInitialSize(64 * 1024 * 1024)
        .setMaxSize(128 * 1024 * 1024).setName(PERSISTENT_REGION_NAME);

DataStorageConfiguration dataStorageConfiguration = new DataStorageConfiguration().setDefaultDataRegionConfiguration(persistence);

//Persistence location config
dataStorageConfiguration.setWalPath(STORAGE_LOCATION + "/wal")
        .setWalArchivePath(STORAGE_LOCATION + "/wal-arc")
        .setStoragePath(STORAGE_LOCATION + "/store");

igniteConfiguration.setDataStorageConfiguration(dataStorageConfiguration);

ignite = Ignition.getOrStart(igniteConfiguration);
ignite.cluster().active(true);

store = ignite.getOrCreateCache(new CacheConfiguration<String, Set<Model>>()
        .setDataRegionName(PERSISTENT_REGION_NAME)
        .setCacheMode(CacheMode.REPLICATED)
        .setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL)
        .setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_SYNC)
        .setName("store")
        .setIndexedTypes(String.class, Set.class)
);

解决方案

看起来 IGNITE_HOME 目录是指重新启动时清除的卷/文件夹。请将该变量设置为未更改的路径，以重新启动存储和 WAL 的方式。
