Description

When persistence is enabled and node restarts, platform cache is empty and remains empty even after read operations.

var cfg = new IgniteConfiguration
{
    DataStorageConfiguration = new DataStorageConfiguration
    {
        DefaultDataRegionConfiguration = new DataRegionConfiguration
        {
            Name = DataStorageConfiguration.DefaultDataRegionName,
            PersistenceEnabled = true
        }
    }
};

var cacheCfg = new CacheConfiguration
{
    Name = "c",
    PlatformCacheConfiguration = new()
};

using (var ignite = Ignition.Start(cfg))
{
    ignite.GetCluster().SetActive(true);

    var cache = ignite.GetOrCreateCache<int, int>(cacheCfg);
    cache[1] = 1;
    Console.WriteLine(">>> Cache size:" + cache.GetSize());
    Console.WriteLine(">>> Platform cache size:" + cache.GetLocalSize(CachePeekMode.Platform));
}

using (var ignite = Ignition.Start(cfg))
{
    ignite.GetCluster().SetActive(true);

    var cache = ignite.GetOrCreateCache<int, int>(cacheCfg);
    Console.WriteLine(">>> Cache size:" + cache.GetSize());
    Console.WriteLine(">>> Platform cache size:" + cache.GetLocalSize(CachePeekMode.Platform));
}
