Hi, Looks like something wrong with you serialization scheme. In case if you are going to store some C++ object you should implement the READ and WRITE methods like here:
https://apacheignite-cpp.readme.io/docs/serialization#section-macros Could you please provide the cache configuration and implementation (.h, .cpp) of your classes that will be used as key, value or part of the key, value object? Also, provide their serialization schemes. BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
