Hello!
I suggest generating a surrogate affinity key in this case, such as
@AffinityKeyMapped String affKey = key1 + "-" + key2;
You can also file a feature request against Apache Ignite JIRA, but given
the lack of community interest towards indexing nested objects, it is
unlikely to be done.
Maybe we could have composite affinity keys eventually, but I can't bet on
that.
Regards,
