Hi Kenan, Either your *examples.cassandra_persistence_store.model.TestResponse* implementation is incorrect or you just accidentally inserting incorrect values into your Cassandra table.
Here are the details: 1) *col5* field in *TestResponse* class has *long* type - which means that it's not nullable. 2) At the same time, all the rows you inserting in Cassandra table have *col5* value as a *null*. Which automatically means that it's impossible to create *TestResponse* object instance from any of these rows, cause *col5* is not nullable. 3) Because of this, all attempts of *CassandraCacheStore* to deserialize *TestResponse* objects inserted into Cassandra table will fail. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
