Hi Roger, Currently this is not possible. If POJO strategy is used, classes need to be deployed. There is a ticket to improve this: https://issues.apache.org/jira/browse/IGNITE-5270
If it's an option for you, you can switch to BLOB strategy and store values in binary from in Cassandra. In this case you don't need to deploy classes. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Cassandra-Persistence-Store-without-POJO-on-Server-tp16412p16413.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
