Are there any general ballpark guidelines as to how many consumer connections a single broker can handle? Generally guidance is that you should stick to 2-4k max partitions per broker. Does that mean that a broker can handle on the order of ~2k consumers listening to partitions on that broker? Or is the number smaller (i.e. in the 100’s)?
It’s not so much about number of consumers, more number of tcp connections. ~10k tends to be the uppper limit
