using user defined object as key in ignite c++ client
Hi.. I was able to run a sample c++ client program , loading/retrieving cache
from a table in persistent store. The table has just one int field as
primary key and for cache I configured this primary key int as the cache
key. But now I want to use cache for table in persistent store which have
combination of different fields as primary key. What should I use as a cache
key in this situation? Just like I used POJO to map cache values, should I
use another POJO for cache keys?If so how should I map cache key POJO to
c++?

Hi,
You need to declare matching class in C++ and specialize
BinaryType template for it as described at [1].
You can find which type in C++ matches which type from
Java at [2].

Best Regards,
