We now use LettuceInvoker to call Lettuce API methods for synchronous, pipelining, and transactional execution models. LettuceInvoker captures the method invocation as functional utility and allows conversion of results:
Long result = invoker.just(RedisGeoAsyncCommands::geoadd, key, point.getX(), point.getY(), member);
List<byte[]> result = invoker.fromMany(RedisGeoAsyncCommands::geohash, key, members)
.toList(it -> it.getValueOrElse(null));
