If you execute in-memory SQL queries using Ignite API, you have to load the data from the store first: https://apacheignite.readme.io/docs/data-loading#ignitecacheloadcache Read-through works only for key based access. With queries you don't know set of required keys in advance, thus only data which is already in memory is used to execute them. -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Newbie-Questions-on-Ignite-over-cassandra-tp10264p10268.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
