创建Group ID用于消费者订阅消息

Group表示一类Producer或Consumer，这类Producer或Consumer通常生产或消费同一类消息，且消息发布或订阅的逻辑一致。使用云消息队列 RocketMQ 版进行消息收发，您需要创建Group ID用于标识同一类生产者实例或者同一类消费者实例。本文介绍如何在云消息队列 RocketMQ 版控制台上创建、删除和查询Group。

大佬们，问下RocketMQ抢购功能，消费者处理逻辑怎么能拿到抢单者信息？类似美团众包，有个抢单功能

大佬们，问下RocketMQ抢购功能，消费者处理逻辑怎么能拿到抢单者信息？类似美团众包，有个抢单功能，客户下单支付后，我是发mq给所有骑手，一个订单只能被一名骑手接单。是不是得通过前端点击抢单按钮来触发消费逻辑？
