The underlying Dynamo architecture is great, and original Facebook and community releases did deliver on the overall promises. Unfortunately the implementations suffered, partly because of the language and baggage from Java and from the execution model.

Scylla using C++ helped in bringing the low-level planning and development experience that is common in that area (and harder to do in Java), but also the ability to use all the low-level libraries like DPDK and advanced threading/reactor systems (like the underlying Seastar framework that Scylla made).

The opensource Cassandra versions are now implementing the same model, although still using Java.
