How does Apache Ignite supports partitioning?
I am trying to experiment with data partition in Apache Ignite using .NET thin client.
In article https://apacheignite.readme.io/docs/cache-modes it’s written that in partition mode "the overall data set is divided equally into partitions and all partitions are split equally between participating nodes". So I am expecting cache with 1000 records to be splitted beetween 3 Ignite nodes equally: 333(4) on each node. But when I start 3 instances of Ignite on local machine (using platforms\dotnet\bin\Apache.Ignite.exe) I can see only that 1000 records are replicated on all nodes: 1000 same records on each node. I tried to disable backups creation: 1000 records were created only on first node. Currently I use sequental Int32 values as cache key. But even when I ran LinqExample with colocated employes (with AffinityKey) data was’t splitted beetween nodes.
I also tried to experiment with cache configuration:
var cacheConfiguration = new CacheClientConfiguration(_key, cacheEntity); cacheConfiguration.CacheMode = CacheMode.Partitioned; cacheConfiguration.Backups = 0; cacheConfiguration.ReadFromBackup = false; cacheConfiguration.RebalanceMode = CacheRebalanceMode.Sync; cacheConfiguration.RebalanceOrder = 1; cacheConfiguration.RebalanceThrottle = TimeSpan.FromSeconds(1); cacheConfiguration.RebalanceDelay = TimeSpan.Zero; cacheConfiguration.RebalanceBatchSize = 1024; var cache = _igniteClient.CreateCache<int, TEntityType>(cacheConfiguration).WithExpiryPolicy(_expiryPolicy); Perhaps I don’t understand the main concept of data partitioning implemented in Apache Ignite or Apache.Ignite.exe needs some additional configuration to support data partitioning. Execuse me if it’s a simple question.
PS. I am using DBeaver to check amount of records on each node. 3 ignite instances by default uses ports 10800, 10801, 10802 for .NET client requests. So I am using localhost:10800, localhost:10801, localhost:10802 adresses in DBeaver.
