我的嵌入式Ignite（v2.3）服务具有以下配置（最终它将成为集群，但嵌入式更易于开发）：
val config = new IgniteConfiguration
val dsConfig = new DataStorageConfiguration
dsConfig.setStoragePath("ignitedb/storage")
dsConfig.setWalPath("ignitedb/wal")
dsConfig.setWalArchivePath("ignitedb/wal/archive")
dsConfig.getDefaultDataRegionConfiguration.setPersistenceEnabled(true)
config.setDataStorageConfiguration(dsConfig)
Ignition.setClientMode(false)
config.setConsistentId(java.net.InetAddress.getLocalHost.getHostName)
val ignite = Ignition.start(config)
ignite.active(true)
在这些目录中创建了各种文件：

然而，当我停止并重启我的应用程序时，我的所有缓存都消失了。我如何实际将它们保存到磁盘？我是否需要为每个缓存执行某些操作以及在全局范围内启用持久性？ （文档中没有提到类似的内容。）
我在启动时遇到这个异常，经过仔细检查看起来它来自持久层：

答案 0 :(得分：1)
问题是我的缓存名称中的/导致持久层创建了额外的目录，因为它们根本没有被转义。我转而使用@，现在看起来很好。
