While Bloom was indeed coded in ruby, they use C++ for Anna: > We get this rich consistency in Anna with a very clean codebase, by porting design patterns of monotone lattice composition from Bloom to C++. In the paper: > The Anna actor and client proxy are implemented entirely in C++. The codebase—including the lattice library, all the consistency levels, the server code, and client proxy code— amounts to about 2000 lines of C++ on top of commonly-used libraries including ZeroMQ and Google Protocol Buffers.
