Hi, loadCache(..) is designed to load the cache from a 3rd party store.
you are not setting the cache factory in your app. See: https://apacheignite.readme.io/docs/3rd-party-store#rdbms-integration example: https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/datagrid/store/jdbc/CacheJdbcStoreExample.java it has: cacheCfg.setCacheStoreFactory(FactoryBuilder.factoryOf(CacheJdbcPersonStore.class)); this tell loadCache(..) where to get the data from.
