[jira] [Commented] (IGNITE-8448) C++: AffinityKey support

["Ilya Kasnacheev (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-8448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16466176#comment-16466176 ] 

Ilya Kasnacheev commented on IGNITE-8448:
-----------------------------------------

Currently, a workaround should be available by setting cacheConfiguration.setKeyConfiguration() to a custom CacheKeyConfiguration (in Java config or XML).

But it would be more direct to just be able to specify affinity key in C++.

Otherwise, a following error is reported:
{code}
An error occurred: Java exception occurred [cls=org.apache.ignite.binary.BinaryObjectException, msg=Binary type has different affinity key fields [typeName=KeyType, affKeyFieldName1=affId, affKeyFieldName2=null]]
{code}
