Hi Tim, Cache configuration is defines when it's started. So @QuerySqlField annotation on the new field does not have affect unless you restart the cluster or at least destroy the cache and create with the new configuration. Field are added on object level transparently, but to modify the SQL schema in runtime you need to use ALTER TABLE and CREATE INDEX: https://apacheignite-sql.readme.io/docs/ddl
