I am trying Apache ignite, but I could not put the object data. The server is a single node in Java. The client is a thin client in .NET(C#).
This version is
Server OS:Ubuntu 18.04
JAVA:openjdk version 11.0.11
ignite:2.10.0
Client OS:Windows 10
.NET:.NET Framework 4.6.2
ignite:2.10.0 (Nuget)
When the client put the object, the following exception is raised.
Apache.Ignite.Core.Client.IgniteClientException
HResult=0x80131500
Message=class org.apache.ignite.internal.processors.cache.CachePartialUpdateCheckedException: Failed to update keys (retry update if possible).: [100]

The same exception occurred on the server.

The client source is as follows:
var cfg = new IgniteClientConfiguration {
Endpoints = new[] { "10.1.1.1:10800" },
BinaryConfiguration=new BinaryConfiguration() {
CompactFooter=true,
NameMapper= new BinaryBasicNameMapper { IsSimpleName = true }
}
};
using (var client = Ignition.StartClient(cfg)) {
client.GetBinary().GetBinaryType(typeof(Patient));
var cache = client.GetOrCreateCache<string, Patient>("PatientCache");
var pat = new Patient() { PatientId = "100", Name = "Test", Birthday = new DateTime(1980,5,1) };
pat.Birthday = pat.Birthday.ToUniversalTime();
cache.Put("100", pat);
}
using (var client = Ignition.StartClient(cfg)) {
var cache = client.GetOrCreateCache<string, Patient>("PatientCache");
var pat = cache.Get("100");
System.Diagnostics.Debug.WriteLine("Patient:{0},{1},{2}",pat.PatientId,pat.Name,pat.Birthday);
}
When the data to be registered is a string, it was registered successfully. I am having trouble figuring out what is causing this.
Cache update fails on the server because Patient class is not serializable:
NotSerializableException: ignitetest.Patient
Make ignitetest.Patient serializable to fix the issue.
See the inner exception in the log - CacheJdbcBlobStore fails to write an object:
