Hello, You can use org.apache.ignite.cache.store.jdbc.CacheJdbcBlobStore instand of CacheJdbcPojoStore In the case key and value will be serialized to byte array and wrote to database (in ENTRIES table).
Other way (for CacheJdbcPojoStore) you can use java.sql.Types#ARRAY like this new JdbcTypeField(Types.ARRAY, "ARR", String.class, "arr")) or in xml.
