Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
memberlist
- library for gossip coordination

Is it possible to have more than 1 master available for writes in a raft system?
I use lightweight https://github.com/hashicorp/memberlist to build initial cluster skeleton (find out what are nodes constituting it)
-
Leaderless consensus protocol in the wild
Does https://github.com/hashicorp/memberlist count? It’s a gossip-based eventual consistency protocol based on SWIM.

What sort of mature, open-source libraries do you feel Rust should have but currently lacks?
An equivalent of golang's memberlist would be awesome.
-
What's the biggest outage you have ever caused?
I don't know the engineer that did it but I know what happened. There's a library that a bunch of foundational Amazon services use called DFDD. It uses a gossip protocol to handle service discovery and health checking. The open source equivalent is Hashicorp memberlist. To remove a node from the cluster, you have to send a command to an arbitrary node that says a node is dead.

Service discovery library in Rust?
serf uses memberlist which uses the SWIM failure detection protocol (https://www.cs.cornell.edu/projects/Quicksilver/public_pdfs/SWIM.pdf) with the Lifeguard extensions (https://arxiv.org/pdf/1707.00788.pdf).

Ask HN: Which are the best go repositories to read to learn the language?
https://github.com/hashicorp/memberlist
Fairly idiomatic/clean

A Spanner-based distributed locking library
This algorithm assumes you're doing that separately using some sort of membership protocol (e.g. SWIM), and you pass in the membership list that you are keeping up to date with that protocol. If you're curious about those, HashiCorp memberlist and HashiCorp Serf are really good to look at. I believe Consul uses those libraries under the hood.

Service discovery library in Rust?
It comes with Rust (https://github.com/ipgen/rust) and Go (https://github.com/ipgen/go) reference implementations. It also has a command line tool written in Rust (https://github.com/ipgen/cli).
