Hi Kenan, SQL queries are executed against the data that is in memory. Read-though semantics works for key-based access only. If you need to query data that is both in memory and on disk, I'd recommend to take a look at Ignite native persistence: https://apacheignite.readme.io/docs/distributed-persistent-store
