code: public static void registerOptimization(SimpleConfiguration appConfig, String key,
        Class<? extends TableOptimizationsFactory> clazz) {
      appConfig.setProperty(PREFIX + key, clazz.getName());
    }
docs: This method provides a standard way to register a table optimization for the Fluo table before
  initialization. After Fluo is initialized, the optimizations can be retrieved by calling
  {@link #getConfiguredOptimizations(FluoConfiguration)}.
  
  @param appConfig config, likely obtained from calling
  {@link FluoConfiguration#getAppConfiguration()}
  @param key A unique identifier for the optimization
  @param clazz The optimization factory type.
