I feel like I'd like to see that with data. Because every Ops session
I've been in around logging and debugging has had nearly everyone raise
their hand that they are running the ELK stack for log analysis. So they
are all running Java already.
I would absolutely hate to have some design point get made based on
rumors from ops and "java is icky" sentiment from the dev space.
Defaults matter, because it means you get a critical mass of operators
running similar configs, and they can build and share knowledge. For all
of the issues with Rabbit, it has demonstrably been good to have
collaboration in the field between operators that have shared patterns
and fed back the issues. So we should really say Zookeeper is the
default choice, even if there are others people could choose that have
extra mustachy / monocle goodness.
