Hacked up the client to (1) consume messages continuously in a separate goroutine to keep our local buffers full and (2) prefer sending messages from topics in higher priority groups, over messages from topics in lower priority groups. Why? This was an ask for use cases where bandwidth can be limited, and you want to be able to prioritize delivery/replication of certain important messages over less important ones that can wait until later to catch up.

Not meant for merging or production (yet?), just as a potential idea.
I hacked up the client to (1) prefer sending messages from topics in higher priority groups, over messages from topics in lower priority groups and (2) consume messages continuously in a separate goroutine to keep our local buffers full. It's super messy and has some config hard-coded in but shows that the basic algorithm works.
Why? This was an ask for use cases where bandwidth can be limited, and you want to be able to prioritize delivery/replication of important messages back to the centralized cluster until you get more bandwidth or the production of important messages slows down.
