> .NET: wrong affinity key registration with AffinityKeyMapped attribute
> ----------------------------------------------------------------------
>
> Key: IGNITE-13160
> URL: https://issues.apache.org/jira/browse/IGNITE-13160
> Project: Ignite
> Issue Type: Bug
> Components: platforms
> Affects Versions: 2.8.1
> Reporter: Alexandr Shapkin
> Assignee: Pavel Tupitsyn
> Priority: Major
> Fix For: 2.10
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> When QueryEntities is set alongside a custom key that utilizes the
> AffinityKeyMapped attribute, the field won't be taken into account for some
> reason. When QueryEntities configuration gets removed, all works fine,
> setting KeyConfiguration manually helps as well. At the same time, the
> BinaryType registration itself looks fine.
> After the investigation, it turned out that affinityKey field is not being
> registered on cache registration, and null is being cached instead. Later on
> Ignite correctly tries to register a custom class as a key, but it's never
> being updated internally case the real value is already cached.
>
> NOTE: there is a workaround - you need to specify the key configuration
> explicitly:
> {code:java}
> cacheConfiguration.KeyConfiguration = new List<CacheKeyConfiguration>(1)
> {
> //affinityKey should be auto adjusted with Reflection
> new CacheKeyConfiguration(typeof(MyKey))
> };
>
> {code}
>
> Reproducer (add to the AffinityTest.cs):
> {code:java}
> /// <summary>
> /// Tests AffinityKeyMapped attribute should map to the same
> partitions
> /// for the same field value.
> /// </summary>
> [Test]
> public void TestCustomAffinity()
> {
> IIgnite g = Ignition.GetIgnite("grid-0");
> var cacheCfg = new CacheConfiguration("mycache")
> {
> // Without QueryEntities tests passes.
> QueryEntities = new List<QueryEntity>()
> {
> new QueryEntity(typeof(MyKey), typeof(int))
> }
> };
> g.GetOrCreateCache<MyKey, int>(cacheCfg);
> var key1 = new MyKey {Data = "data1", AffinityKey = 1};
> var key2 = new MyKey {Data = "data2", AffinityKey = 1};
> ICacheAffinity aff = g.GetAffinity(cacheCfg.Name);
> Assert.AreEqual(aff.GetPartition(key1), aff.GetPartition(key2));
> }
> public class MyKey
> {
> [QuerySqlField]
> public string Data { get; set; }
> [AffinityKeyMapped]
> public long AffinityKey { get; set; }
> }
> {code}
