I thought batched messages were not supported. Can anyone confirm?

I think "Scheduled message," "Ordered message," and "Transactional message" are definitely supported, but I might be mixing up some details.

Wait, are retried messages actually a supported type? Sounds off.

I'm a bit confused by this question. There are a lot of message types listed, and I'm not sure which ones are specific to Alibaba Cloud RocketMQ. I'll try to eliminate the ones that don't sound like they'd be supported, but I'm not feeling super confident about this one.

Okay, I've got this! Scheduled messages, ordered messages, and batched messages are definitely supported by RocketMQ. I'm pretty confident about those three. The other two options seem a bit less clear, so I'll have to think about them a bit more.

Hmm, I'm not too familiar with Alibaba Cloud RocketMQ, so I'll need to think this through carefully. Let me try to recall what I know about message types in general and see if that helps me narrow down the options.

Okay, let's see here. I know RocketMQ is designed for high-performance messaging, so I'm guessing the supported message types will be things like scheduled, ordered, and batched messages. I'll make sure to select those options.

Batched message can improve efficiency by sending multiple messages in one batch, reducing overhead. So, it could be a valid option for high performance requirements.
