> Is bazel build distributed?

Yes, that's the main feature of Bazel. And it caches the generated files. Although you could do theoretically cache using ccache with distcc.

I doubt that it is the main feature. RBE is difficult to deploy and consequently rarely used. On the other hand of you assume that 99% of bazel invocations are done by google, then weighted that way RBE is nearly universal.
