What are those some of the good Apache projects? Practically never used anything but httpd (which I no longer use) and everything else looked like bloated software being Java taking huge resource and usually has a better competitor. I occasionally see Kafka being used as parts of software stack but not sure if that is the best choice with huge resource use.
