Re: Error CacheConfig

Hi,

You need to configure indexing to use queries. For that you may use
CacheConfiguration.setIndexedTypes() or setup QueryEntity [1, 2].

For example, if you configuring cache with Integer key and String value:
CacheConfiguration<Integer, String> cfg = new
CacheConfiguration<>("cache-name");
cfg.setIndexedTypes(Integer.class, String.class);

After that you will be able to perform SQL queries on it.

For custom key/value use mentioned above annotations or QueryEntity, f.e.:

public class Key {
  @QuerySqlField
  private String key;
}

public class Value {
  @QuerySqlField
  private String value;
}

cfg.setIndexedTypes(Key.class, Value.class);
