I quite like this idea, as we're currently doing something similar (given
that I understand your suggestion correctly), albeit with the LeaderLatch.

In our case, each node sets a watch on each latch znode and populate/change
a local “cache” (more like a registry) when the children of a latch znode
change (but only if it’s possible to actually get a leader from

I suppose it would also be possible have a non-static method that fulfils
the same purpose as well, no?
