Looks like type metadata for cache is not configured. Please check CacheConfiguration class. It should contains the next method: /** * Create JDBC type for Person. * * @param cacheName Cache name. * @return Configured JDBC type. */ private static JdbcType jdbcTypePerson(String cacheName) { JdbcType jdbcType = new JdbcType(); jdbcType.setCacheName(cacheName); jdbcType.setDatabaseSchema("PUBLIC"); jdbcType.setDatabaseTable("PERSON"); jdbcType.setKeyType("org.apache.ignite.PersonKey"); jdbcType.setValueType("org.apache.ignite.Person"); jdbcType.setKeyFields( new JdbcTypeField(Types.NUMERIC, "ID", long.class, "id") ); jdbcType.setValueFields( new JdbcTypeField(Types.VARCHAR, "FIRST_NAME", String.class, "firstName"), new JdbcTypeField(Types.VARCHAR, "LAST_NAME", String.class, "lastName"), new JdbcTypeField(Types.DOUBLE, "SALARY", Double.class, "salary") ); return jdbcType; } that used in "cache" method in the following way: // Configure JDBC types. Collection<JdbcType> jdbcTypes = new ArrayList<>(); jdbcTypes.add(jdbcTypePerson(cacheName)); storeFactory.setTypes(jdbcTypes.toArray(new JdbcType[jdbcTypes.size()])); That configuration work perfectly for me with H2 database. If my answer does not help to you please provide full source code of your example. -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Failed-to-find-mapping-description-cache-PersonCache-typeId-class-apache-ignite-schemas-PersonKey-PlR-tp3725p3731.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
