Re: Cassandra and Ignite C++ Issue
User's comment:
I have my own cassandra table with 1 partiton key, 3 clustering keys,
and I expect the value not to be stored in one column as a blob.
Is there any way I can achieve this?
I have used POJO and there is an issue like the key is only getting
inserted into the cassandra table
Best Regards,
Igor

Could you share your POJO key/value classes and persistence descriptor?
