Building Distributed Systems Amongst Stateright
Stateright is a model checker for distributed systems. It is provided every bit a Rust library, in addition to it allows y'all to verify systems implemented inward Rust. It is openly available on GitHub in addition to the developer, Jon Nadal, is looking for contributors in addition to novel users.
On Tuesday Jon gave a presentation to us on Zoom. He made his presentation slides available here. We convey too recorded Jon's presentation in addition to the Q&A in addition to demonstrate sessions inward entirety.
The highlights of Stateright are:
- great visualization support,
- time go debugger: which helps y'all become back/forth in addition to direct to explore about other branch from a given betoken of the electrical flow execution (in the Figure below, the Next Steps heading supply possible adjacent steps to direct from),
- an actor-based model,
- an embedded linearizability tester,
- and extensive docs in addition to Rust mass for introducing the concepts.
The model trait has state, init_states, actions, next_state, in addition to properties.
Similarly at that spot is an musician trait y'all tin implement, in addition to model cheque every bit follows.
The Rust mass for Stateright gives examples of model checking ABD protocol inward Rust in addition to the chapter on Paxos protocol is coming soon.
To ameliorate the functioning of model checking, the checker fingerprints states in addition to digests states into 64 chip integers. Rust is too a fast linguistic communication because it does non create much pointer hopping. Jon said he volition endeavor to implement dynamic partial guild reduction to ameliorate the functioning of model checking further. The model checker is already parallel, only running on many machines inward a distributed fashion tin too endure added.
