Hi folks, Recently I'm working on the implementation of PIP-37, see https://github.com/apache/pulsar/wiki/PIP-37%3A-Large-message-size-handling-in-Pulsar#usecase-3-multiple-producers-with-shared-consumers
As we can see, https://github.com/apache/pulsar/pull/4400 only implements chunking messages with non-shared subscriptions. When I followed the **Option 2** section, I found it works but there are many details that need to be taken care of. For example, - Should we add a marker type to indicate the chunk marker? - Normally, the markers like Transaction markers are not visible to the client, but we need to send the chunk marker to client. - What's the format of the chunk marker? - Which compatibility problems would be brought by this design? I think we need a new proposal to explain it in details and I'm working on that, as well as the demo. Feel free to ping me if you have any concern. Thanks, Yunze
